# The request for BeginTransaction.
class BeginTransactionRequest
include Google::Apis::Core::Hashable
# # Transactions Each session can have at most one active transaction at a time (
# note that standalone reads and queries use a transaction internally and do
# count towards the one transaction limit). After the active transaction is
# completed, the session can immediately be re-used for the next transaction. It
# is not necessary to create a new session for each transaction. # Transaction
# Modes Cloud Spanner supports three transaction modes: 1. Locking read-write.
# This type of transaction is the only way to write data into Cloud Spanner.
# These transactions rely on pessimistic locking and, if necessary, two-phase
# commit. Locking read-write transactions may abort, requiring the application
# to retry. 2. Snapshot read-only. This transaction type provides guaranteed
# consistency across several reads, but does not allow writes. Snapshot read-
# only transactions can be configured to read at timestamps in the past.
# Snapshot read-only transactions do not need to be committed. 3. Partitioned
# DML. This type of transaction is used to execute a single Partitioned DML
# statement. Partitioned DML partitions the key space and runs the DML statement
# over each partition in parallel using separate, internal transactions that
# commit independently. Partitioned DML transactions do not need to be committed.
# For transactions that only read, snapshot read-only transactions provide
# simpler semantics and are almost always faster. In particular, read-only
# transactions do not take locks, so they do not conflict with read-write
# transactions. As a consequence of not taking locks, they also do not abort, so
# retry loops are not needed. Transactions may only read/write data in a single
# database. They may, however, read/write data in different tables within that
# database. ## Locking Read-Write Transactions Locking transactions may be used
# to atomically read-modify-write data anywhere in a database. This type of
# transaction is externally consistent. Clients should attempt to minimize the
# amount of time a transaction is active. Faster transactions commit with higher
# probability and cause less contention. Cloud Spanner attempts to keep read
# locks active as long as the transaction continues to do reads, and the
# transaction has not been terminated by Commit or Rollback. Long periods of
# inactivity at the client may cause Cloud Spanner to release a transaction's
# locks and abort it. Conceptually, a read-write transaction consists of zero or
# more reads or SQL statements followed by Commit. At any time before Commit,
# the client can send a Rollback request to abort the transaction. ### Semantics
# Cloud Spanner can commit the transaction if all read locks it acquired are
# still valid at commit time, and it is able to acquire write locks for all
# writes. Cloud Spanner can abort the transaction for any reason. If a commit
# attempt returns `ABORTED`, Cloud Spanner guarantees that the transaction has
# not modified any user data in Cloud Spanner. Unless the transaction commits,
# Cloud Spanner makes no guarantees about how long the transaction's locks were
# held for. It is an error to use Cloud Spanner locks for any sort of mutual
# exclusion other than between Cloud Spanner transactions themselves. ###
# Retrying Aborted Transactions When a transaction aborts, the application can
# choose to retry the whole transaction again. To maximize the chances of
# successfully committing the retry, the client should execute the retry in the
# same session as the original attempt. The original session's lock priority
# increases with each consecutive abort, meaning that each attempt has a
# slightly better chance of success than the previous. Under some circumstances (
# e.g., many transactions attempting to modify the same row(s)), a transaction
# can abort many times in a short period before successfully committing. Thus,
# it is not a good idea to cap the number of retries a transaction can attempt;
# instead, it is better to limit the total amount of wall time spent retrying. ##
# # Idle Transactions A transaction is considered idle if it has no outstanding
# reads or SQL queries and has not started a read or SQL query within the last
# 10 seconds. Idle transactions can be aborted by Cloud Spanner so that they don'
# t hold on to locks indefinitely. In that case, the commit will fail with error
# `ABORTED`. If this behavior is undesirable, periodically executing a simple
# SQL query in the transaction (e.g., `SELECT 1`) prevents the transaction from
# becoming idle. ## Snapshot Read-Only Transactions Snapshot read-only
# transactions provides a simpler method than locking read-write transactions
# for doing several consistent reads. However, this type of transaction does not
# support writes. Snapshot transactions do not take locks. Instead, they work by
# choosing a Cloud Spanner timestamp, then executing all reads at that timestamp.
# Since they do not acquire locks, they do not block concurrent read-write
# transactions. Unlike locking read-write transactions, snapshot read-only
# transactions never abort. They can fail if the chosen read timestamp is
# garbage collected; however, the default garbage collection policy is generous
# enough that most applications do not need to worry about this in practice.
# Snapshot read-only transactions do not need to call Commit or Rollback (and in
# fact are not permitted to do so). To execute a snapshot transaction, the
# client specifies a timestamp bound, which tells Cloud Spanner how to choose a
# read timestamp. The types of timestamp bound are: - Strong (the default). -
# Bounded staleness. - Exact staleness. If the Cloud Spanner database to be read
# is geographically distributed, stale read-only transactions can execute more
# quickly than strong or read-write transaction, because they are able to
# execute far from the leader replica. Each type of timestamp bound is discussed
# in detail below. ### Strong Strong reads are guaranteed to see the effects of
# all transactions that have committed before the start of the read. Furthermore,
# all rows yielded by a single read are consistent with each other -- if any
# part of the read observes a transaction, all parts of the read see the
# transaction. Strong reads are not repeatable: two consecutive strong read-only
# transactions might return inconsistent results if there are concurrent writes.
# If consistency across reads is required, the reads should be executed within a
# transaction or at an exact read timestamp. See TransactionOptions.ReadOnly.
# strong. ### Exact Staleness These timestamp bounds execute reads at a user-
# specified timestamp. Reads at a timestamp are guaranteed to see a consistent
# prefix of the global transaction history: they observe modifications done by
# all transactions with a commit timestamp <= the read timestamp, and observe
# none of the modifications done by transactions with a larger commit timestamp.
# They will block until all conflicting transactions that may be assigned commit
# timestamps <= the read timestamp have finished. The timestamp can either be
# expressed as an absolute Cloud Spanner commit timestamp or a staleness
# relative to the current time. These modes do not require a "negotiation phase"
# to pick a timestamp. As a result, they execute slightly faster than the
# equivalent boundedly stale concurrency modes. On the other hand, boundedly
# stale reads usually return fresher results. See TransactionOptions.ReadOnly.
# read_timestamp and TransactionOptions.ReadOnly.exact_staleness. ### Bounded
# Staleness Bounded staleness modes allow Cloud Spanner to pick the read
# timestamp, subject to a user-provided staleness bound. Cloud Spanner chooses
# the newest timestamp within the staleness bound that allows execution of the
# reads at the closest available replica without blocking. All rows yielded are
# consistent with each other -- if any part of the read observes a transaction,
# all parts of the read see the transaction. Boundedly stale reads are not
# repeatable: two stale reads, even if they use the same staleness bound, can
# execute at different timestamps and thus return inconsistent results.
# Boundedly stale reads execute in two phases: the first phase negotiates a
# timestamp among all replicas needed to serve the read. In the second phase,
# reads are executed at the negotiated timestamp. As a result of the two phase
# execution, bounded staleness reads are usually a little slower than comparable
# exact staleness reads. However, they are typically able to return fresher
# results, and are more likely to execute at the closest replica. Because the
# timestamp negotiation requires up-front knowledge of which rows will be read,
# it can only be used with single-use read-only transactions. See
# TransactionOptions.ReadOnly.max_staleness and TransactionOptions.ReadOnly.
# min_read_timestamp. ### Old Read Timestamps and Garbage Collection Cloud
# Spanner continuously garbage collects deleted and overwritten data in the
# background to reclaim storage space. This process is known as "version GC". By
# default, version GC reclaims versions after they are one hour old. Because of
# this, Cloud Spanner cannot perform reads at read timestamps more than one hour
# in the past. This restriction also applies to in-progress reads and/or SQL
# queries whose timestamp become too old while executing. Reads and SQL queries
# with too-old read timestamps fail with the error `FAILED_PRECONDITION`. ##
# Partitioned DML Transactions Partitioned DML transactions are used to execute
# DML statements with a different execution strategy that provides different,
# and often better, scalability properties for large, table-wide operations than
# DML in a ReadWrite transaction. Smaller scoped statements, such as an OLTP
# workload, should prefer using ReadWrite transactions. Partitioned DML
# partitions the keyspace and runs the DML statement on each partition in
# separate, internal transactions. These transactions commit automatically when
# complete, and run independently from one another. To reduce lock contention,
# this execution strategy only acquires read locks on rows that match the WHERE
# clause of the statement. Additionally, the smaller per-partition transactions
# hold locks for less time. That said, Partitioned DML is not a drop-in
# replacement for standard DML used in ReadWrite transactions. - The DML
# statement must be fully-partitionable. Specifically, the statement must be
# expressible as the union of many statements which each access only a single
# row of the table. - The statement is not applied atomically to all rows of the
# table. Rather, the statement is applied atomically to partitions of the table,
# in independent transactions. Secondary index rows are updated atomically with
# the base table rows. - Partitioned DML does not guarantee exactly-once
# execution semantics against a partition. The statement will be applied at
# least once to each partition. It is strongly recommended that the DML
# statement should be idempotent to avoid unexpected results. For instance, it
# is potentially dangerous to run a statement such as `UPDATE table SET column =
# column + 1` as it could be run multiple times against some rows. - The
# partitions are committed automatically - there is no support for Commit or
# Rollback. If the call returns an error, or if the client issuing the
# ExecuteSql call dies, it is possible that some rows had the statement executed
# on them successfully. It is also possible that statement was never executed
# against other rows. - Partitioned DML transactions may only contain the
# execution of a single DML statement via ExecuteSql or ExecuteStreamingSql. -
# If any error is encountered during the execution of the partitioned DML
# operation (for instance, a UNIQUE INDEX violation, division by zero, or a
# value that cannot be stored due to schema constraints), then the operation is
# stopped at that point and an error is returned. It is possible that at this
# point, some partitions have been committed (or even committed multiple times),
# and other partitions have not been run at all. Given the above, Partitioned
# DML is good fit for large, database-wide, operations that are idempotent, such
# as deleting old rows from a very large table.

# timestamp among all replicas needed to serve the read. In the second phase,
# reads are executed at the negotiated timestamp. As a result of the two phase
# execution, bounded staleness reads are usually a little slower than comparable
# exact staleness reads. However, they are typically able to return fresher
# results, and are more likely to execute at the closest replica. Because the
# timestamp negotiation requires up-front knowledge of which rows will be read,
# it can only be used with single-use read-only transactions. See
# TransactionOptions.ReadOnly.max_staleness and TransactionOptions.ReadOnly.
# min_read_timestamp. ### Old Read Timestamps and Garbage Collection Cloud
# Spanner continuously garbage collects deleted and overwritten data in the
# background to reclaim storage space. This process is known as "version GC". By
# default, version GC reclaims versions after they are one hour old. Because of
# this, Cloud Spanner cannot perform reads at read timestamps more than one hour
# in the past. This restriction also applies to in-progress reads and/or SQL
# queries whose timestamp become too old while executing. Reads and SQL queries
# with too-old read timestamps fail with the error `FAILED_PRECONDITION`. ##
# Partitioned DML Transactions Partitioned DML transactions are used to execute
# DML statements with a different execution strategy that provides different,
# and often better, scalability properties for large, table-wide operations than
# DML in a ReadWrite transaction. Smaller scoped statements, such as an OLTP
# workload, should prefer using ReadWrite transactions. Partitioned DML
# partitions the keyspace and runs the DML statement on each partition in
# separate, internal transactions. These transactions commit automatically when
# complete, and run independently from one another. To reduce lock contention,
# this execution strategy only acquires read locks on rows that match the WHERE
# clause of the statement. Additionally, the smaller per-partition transactions
# hold locks for less time. That said, Partitioned DML is not a drop-in
# replacement for standard DML used in ReadWrite transactions. - The DML
# statement must be fully-partitionable. Specifically, the statement must be
# expressible as the union of many statements which each access only a single
# row of the table. - The statement is not applied atomically to all rows of the
# table. Rather, the statement is applied atomically to partitions of the table,
# in independent transactions. Secondary index rows are updated atomically with
# the base table rows. - Partitioned DML does not guarantee exactly-once
# execution semantics against a partition. The statement will be applied at
# least once to each partition. It is strongly recommended that the DML
# statement should be idempotent to avoid unexpected results. For instance, it
# is potentially dangerous to run a statement such as `UPDATE table SET column =
# column + 1` as it could be run multiple times against some rows. - The
# partitions are committed automatically - there is no support for Commit or
# Rollback. If the call returns an error, or if the client issuing the
# ExecuteSql call dies, it is possible that some rows had the statement executed
# on them successfully. It is also possible that statement was never executed
# against other rows. - Partitioned DML transactions may only contain the
# execution of a single DML statement via ExecuteSql or ExecuteStreamingSql. -
# If any error is encountered during the execution of the partitioned DML
# operation (for instance, a UNIQUE INDEX violation, division by zero, or a
# value that cannot be stored due to schema constraints), then the operation is
# stopped at that point and an error is returned. It is possible that at this
# point, some partitions have been committed (or even committed multiple times),
# and other partitions have not been run at all. Given the above, Partitioned
# DML is good fit for large, database-wide, operations that are idempotent, such
# as deleting old rows from a very large table.

# KeyRange represents a range of rows in a table or index. A range has a start
# key and an end key. These keys can be open or closed, indicating if the range
# includes rows with that key. Keys are represented by lists, where the ith
# value in the list corresponds to the ith component of the table or index
# primary key. Individual values are encoded as described here. For example,
# consider the following table definition: CREATE TABLE UserEvents ( UserName
# STRING(MAX), EventDate STRING(10) ) PRIMARY KEY(UserName, EventDate); The
# following keys name rows in this table: "Bob", "2014-09-23" Since the `
# UserEvents` table's `PRIMARY KEY` clause names two columns, each `UserEvents`
# key has two elements; the first is the `UserName`, and the second is the `
# EventDate`. Key ranges with multiple components are interpreted
# lexicographically by component using the table or index key's declared sort
# order. For example, the following range returns all events for user `"Bob"`
# that occurred in the year 2015: "start_closed": ["Bob", "2015-01-01"] "
# end_closed": ["Bob", "2015-12-31"] Start and end keys can omit trailing key
# components. This affects the inclusion and exclusion of rows that exactly
# match the provided key components: if the key is closed, then rows that
# exactly match the provided components are included; if the key is open, then
# rows that exactly match are not included. For example, the following range
# includes all events for `"Bob"` that occurred during and after the year 2000: "
# start_closed": ["Bob", "2000-01-01"] "end_closed": ["Bob"] The next example
# retrieves all events for `"Bob"`: "start_closed": ["Bob"] "end_closed": ["Bob"]
# To retrieve events before the year 2000: "start_closed": ["Bob"] "end_open": [
# "Bob", "2000-01-01"] The following range includes all rows in the table: "
# start_closed": [] "end_closed": [] This range returns all users whose `
# UserName` begins with any character from A to C: "start_closed": ["A"] "
# end_open": ["D"] This range returns all users whose `UserName` begins with B: "
# start_closed": ["B"] "end_open": ["C"] Key ranges honor column sort order. For
# example, suppose a table is defined as follows: CREATE TABLE
# DescendingSortedTable ` Key INT64, ... ) PRIMARY KEY(Key DESC); The following
# range retrieves all rows with key values between 1 and 100 inclusive: "
# start_closed": ["100"] "end_closed": ["1"] Note that 100 is passed as the

# An Identity and Access Management (IAM) policy, which specifies access
# controls for Google Cloud resources. A `Policy` is a collection of `bindings`.
# A `binding` binds one or more `members` to a single `role`. Members can be
# user accounts, service accounts, Google groups, and domains (such as G Suite).
# A `role` is a named list of permissions; each `role` can be an IAM predefined
# role or a user-created custom role. For some types of Google Cloud resources,
# a `binding` can also specify a `condition`, which is a logical expression that
# allows access to a resource only if the expression evaluates to `true`. A
# condition can add constraints based on attributes of the request, the resource,
# or both. To learn which resources support conditions in their IAM policies,
# see the [IAM documentation](https://cloud.google.com/iam/help/conditions/
# resource-policies). **JSON example:** ` "bindings": [ ` "role": "roles/
# resourcemanager.organizationAdmin", "members": [ "user:mike@example.com", "
# group:admins@example.com", "domain:google.com", "serviceAccount:my-project-id@

# # Transactions Each session can have at most one active transaction at a time (
# note that standalone reads and queries use a transaction internally and do
# count towards the one transaction limit). After the active transaction is
# completed, the session can immediately be re-used for the next transaction. It
# is not necessary to create a new session for each transaction. # Transaction
# Modes Cloud Spanner supports three transaction modes: 1. Locking read-write.
# This type of transaction is the only way to write data into Cloud Spanner.
# These transactions rely on pessimistic locking and, if necessary, two-phase
# commit. Locking read-write transactions may abort, requiring the application
# to retry. 2. Snapshot read-only. This transaction type provides guaranteed
# consistency across several reads, but does not allow writes. Snapshot read-
# only transactions can be configured to read at timestamps in the past.
# Snapshot read-only transactions do not need to be committed. 3. Partitioned
# DML. This type of transaction is used to execute a single Partitioned DML
# statement. Partitioned DML partitions the key space and runs the DML statement
# over each partition in parallel using separate, internal transactions that
# commit independently. Partitioned DML transactions do not need to be committed.
# For transactions that only read, snapshot read-only transactions provide
# simpler semantics and are almost always faster. In particular, read-only
# transactions do not take locks, so they do not conflict with read-write
# transactions. As a consequence of not taking locks, they also do not abort, so
# retry loops are not needed. Transactions may only read/write data in a single
# database. They may, however, read/write data in different tables within that
# database. ## Locking Read-Write Transactions Locking transactions may be used
# to atomically read-modify-write data anywhere in a database. This type of
# transaction is externally consistent. Clients should attempt to minimize the
# amount of time a transaction is active. Faster transactions commit with higher
# probability and cause less contention. Cloud Spanner attempts to keep read
# locks active as long as the transaction continues to do reads, and the
# transaction has not been terminated by Commit or Rollback. Long periods of
# inactivity at the client may cause Cloud Spanner to release a transaction's
# locks and abort it. Conceptually, a read-write transaction consists of zero or
# more reads or SQL statements followed by Commit. At any time before Commit,
# the client can send a Rollback request to abort the transaction. ### Semantics
# Cloud Spanner can commit the transaction if all read locks it acquired are
# still valid at commit time, and it is able to acquire write locks for all
# writes. Cloud Spanner can abort the transaction for any reason. If a commit
# attempt returns `ABORTED`, Cloud Spanner guarantees that the transaction has
# not modified any user data in Cloud Spanner. Unless the transaction commits,
# Cloud Spanner makes no guarantees about how long the transaction's locks were
# held for. It is an error to use Cloud Spanner locks for any sort of mutual
# exclusion other than between Cloud Spanner transactions themselves. ###
# Retrying Aborted Transactions When a transaction aborts, the application can
# choose to retry the whole transaction again. To maximize the chances of
# successfully committing the retry, the client should execute the retry in the
# same session as the original attempt. The original session's lock priority
# increases with each consecutive abort, meaning that each attempt has a
# slightly better chance of success than the previous. Under some circumstances (
# e.g., many transactions attempting to modify the same row(s)), a transaction
# can abort many times in a short period before successfully committing. Thus,
# it is not a good idea to cap the number of retries a transaction can attempt;
# instead, it is better to limit the total amount of wall time spent retrying. ##
# # Idle Transactions A transaction is considered idle if it has no outstanding
# reads or SQL queries and has not started a read or SQL query within the last
# 10 seconds. Idle transactions can be aborted by Cloud Spanner so that they don'
# t hold on to locks indefinitely. In that case, the commit will fail with error
# `ABORTED`. If this behavior is undesirable, periodically executing a simple
# SQL query in the transaction (e.g., `SELECT 1`) prevents the transaction from
# becoming idle. ## Snapshot Read-Only Transactions Snapshot read-only
# transactions provides a simpler method than locking read-write transactions
# for doing several consistent reads. However, this type of transaction does not
# support writes. Snapshot transactions do not take locks. Instead, they work by
# choosing a Cloud Spanner timestamp, then executing all reads at that timestamp.
# Since they do not acquire locks, they do not block concurrent read-write
# transactions. Unlike locking read-write transactions, snapshot read-only
# transactions never abort. They can fail if the chosen read timestamp is
# garbage collected; however, the default garbage collection policy is generous
# enough that most applications do not need to worry about this in practice.
# Snapshot read-only transactions do not need to call Commit or Rollback (and in
# fact are not permitted to do so). To execute a snapshot transaction, the
# client specifies a timestamp bound, which tells Cloud Spanner how to choose a
# read timestamp. The types of timestamp bound are: - Strong (the default). -
# Bounded staleness. - Exact staleness. If the Cloud Spanner database to be read
# is geographically distributed, stale read-only transactions can execute more
# quickly than strong or read-write transaction, because they are able to
# execute far from the leader replica. Each type of timestamp bound is discussed
# in detail below. ### Strong Strong reads are guaranteed to see the effects of
# all transactions that have committed before the start of the read. Furthermore,
# all rows yielded by a single read are consistent with each other -- if any
# part of the read observes a transaction, all parts of the read see the
# transaction. Strong reads are not repeatable: two consecutive strong read-only
# transactions might return inconsistent results if there are concurrent writes.
# If consistency across reads is required, the reads should be executed within a
# transaction or at an exact read timestamp. See TransactionOptions.ReadOnly.
# strong. ### Exact Staleness These timestamp bounds execute reads at a user-
# specified timestamp. Reads at a timestamp are guaranteed to see a consistent
# prefix of the global transaction history: they observe modifications done by
# all transactions with a commit timestamp <= the read timestamp, and observe
# none of the modifications done by transactions with a larger commit timestamp.
# They will block until all conflicting transactions that may be assigned commit
# timestamps <= the read timestamp have finished. The timestamp can either be
# expressed as an absolute Cloud Spanner commit timestamp or a staleness
# relative to the current time. These modes do not require a "negotiation phase"
# to pick a timestamp. As a result, they execute slightly faster than the
# equivalent boundedly stale concurrency modes. On the other hand, boundedly
# stale reads usually return fresher results. See TransactionOptions.ReadOnly.
# read_timestamp and TransactionOptions.ReadOnly.exact_staleness. ### Bounded
# Staleness Bounded staleness modes allow Cloud Spanner to pick the read
# timestamp, subject to a user-provided staleness bound. Cloud Spanner chooses
# the newest timestamp within the staleness bound that allows execution of the
# reads at the closest available replica without blocking. All rows yielded are
# consistent with each other -- if any part of the read observes a transaction,
# all parts of the read see the transaction. Boundedly stale reads are not
# repeatable: two stale reads, even if they use the same staleness bound, can
# execute at different timestamps and thus return inconsistent results.
# Boundedly stale reads execute in two phases: the first phase negotiates a
# timestamp among all replicas needed to serve the read. In the second phase,
# reads are executed at the negotiated timestamp. As a result of the two phase
# execution, bounded staleness reads are usually a little slower than comparable
# exact staleness reads. However, they are typically able to return fresher
# results, and are more likely to execute at the closest replica. Because the
# timestamp negotiation requires up-front knowledge of which rows will be read,
# it can only be used with single-use read-only transactions. See
# TransactionOptions.ReadOnly.max_staleness and TransactionOptions.ReadOnly.
# min_read_timestamp. ### Old Read Timestamps and Garbage Collection Cloud
# Spanner continuously garbage collects deleted and overwritten data in the
# background to reclaim storage space. This process is known as "version GC". By
# default, version GC reclaims versions after they are one hour old. Because of
# this, Cloud Spanner cannot perform reads at read timestamps more than one hour
# in the past. This restriction also applies to in-progress reads and/or SQL
# queries whose timestamp become too old while executing. Reads and SQL queries
# with too-old read timestamps fail with the error `FAILED_PRECONDITION`. ##
# Partitioned DML Transactions Partitioned DML transactions are used to execute
# DML statements with a different execution strategy that provides different,
# and often better, scalability properties for large, table-wide operations than
# DML in a ReadWrite transaction. Smaller scoped statements, such as an OLTP
# workload, should prefer using ReadWrite transactions. Partitioned DML
# partitions the keyspace and runs the DML statement on each partition in
# separate, internal transactions. These transactions commit automatically when
# complete, and run independently from one another. To reduce lock contention,
# this execution strategy only acquires read locks on rows that match the WHERE
# clause of the statement. Additionally, the smaller per-partition transactions
# hold locks for less time. That said, Partitioned DML is not a drop-in
# replacement for standard DML used in ReadWrite transactions. - The DML
# statement must be fully-partitionable. Specifically, the statement must be
# expressible as the union of many statements which each access only a single
# row of the table. - The statement is not applied atomically to all rows of the
# table. Rather, the statement is applied atomically to partitions of the table,
# in independent transactions. Secondary index rows are updated atomically with
# the base table rows. - Partitioned DML does not guarantee exactly-once
# execution semantics against a partition. The statement will be applied at
# least once to each partition. It is strongly recommended that the DML
# statement should be idempotent to avoid unexpected results. For instance, it
# is potentially dangerous to run a statement such as `UPDATE table SET column =
# column + 1` as it could be run multiple times against some rows. - The
# partitions are committed automatically - there is no support for Commit or
# Rollback. If the call returns an error, or if the client issuing the
# ExecuteSql call dies, it is possible that some rows had the statement executed
# on them successfully. It is also possible that statement was never executed
# against other rows. - Partitioned DML transactions may only contain the
# execution of a single DML statement via ExecuteSql or ExecuteStreamingSql. -
# If any error is encountered during the execution of the partitioned DML
# operation (for instance, a UNIQUE INDEX violation, division by zero, or a
# value that cannot be stored due to schema constraints), then the operation is
# stopped at that point and an error is returned. It is possible that at this
# point, some partitions have been committed (or even committed multiple times),
# and other partitions have not been run at all. Given the above, Partitioned
# DML is good fit for large, database-wide, operations that are idempotent, such
# as deleting old rows from a very large table.

# They will block until all conflicting transactions that may be assigned commit

# expressed as an absolute Cloud Spanner commit timestamp or a staleness
# relative to the current time. These modes do not require a "negotiation phase"
# to pick a timestamp. As a result, they execute slightly faster than the
# equivalent boundedly stale concurrency modes. On the other hand, boundedly
# stale reads usually return fresher results. See TransactionOptions.ReadOnly.
# read_timestamp and TransactionOptions.ReadOnly.exact_staleness. ### Bounded
# Staleness Bounded staleness modes allow Cloud Spanner to pick the read
# timestamp, subject to a user-provided staleness bound. Cloud Spanner chooses
# the newest timestamp within the staleness bound that allows execution of the
# reads at the closest available replica without blocking. All rows yielded are
# consistent with each other -- if any part of the read observes a transaction,
# all parts of the read see the transaction. Boundedly stale reads are not
# repeatable: two stale reads, even if they use the same staleness bound, can
# execute at different timestamps and thus return inconsistent results.
# Boundedly stale reads execute in two phases: the first phase negotiates a
# timestamp among all replicas needed to serve the read. In the second phase,
# reads are executed at the negotiated timestamp. As a result of the two phase
# execution, bounded staleness reads are usually a little slower than comparable
# exact staleness reads. However, they are typically able to return fresher
# results, and are more likely to execute at the closest replica. Because the
# timestamp negotiation requires up-front knowledge of which rows will be read,
# it can only be used with single-use read-only transactions. See
# TransactionOptions.ReadOnly.max_staleness and TransactionOptions.ReadOnly.
# min_read_timestamp. ### Old Read Timestamps and Garbage Collection Cloud
# Spanner continuously garbage collects deleted and overwritten data in the
# background to reclaim storage space. This process is known as "version GC". By
# default, version GC reclaims versions after they are one hour old. Because of
# this, Cloud Spanner cannot perform reads at read timestamps more than one hour
# in the past. This restriction also applies to in-progress reads and/or SQL
# queries whose timestamp become too old while executing. Reads and SQL queries
# with too-old read timestamps fail with the error `FAILED_PRECONDITION`. ##
# Partitioned DML Transactions Partitioned DML transactions are used to execute
# DML statements with a different execution strategy that provides different,
# and often better, scalability properties for large, table-wide operations than
# DML in a ReadWrite transaction. Smaller scoped statements, such as an OLTP
# workload, should prefer using ReadWrite transactions. Partitioned DML
# partitions the keyspace and runs the DML statement on each partition in
# separate, internal transactions. These transactions commit automatically when
# complete, and run independently from one another. To reduce lock contention,
# this execution strategy only acquires read locks on rows that match the WHERE
# clause of the statement. Additionally, the smaller per-partition transactions
# hold locks for less time. That said, Partitioned DML is not a drop-in
# replacement for standard DML used in ReadWrite transactions. - The DML
# statement must be fully-partitionable. Specifically, the statement must be
# expressible as the union of many statements which each access only a single
# row of the table. - The statement is not applied atomically to all rows of the
# table. Rather, the statement is applied atomically to partitions of the table,
# in independent transactions. Secondary index rows are updated atomically with
# the base table rows. - Partitioned DML does not guarantee exactly-once
# execution semantics against a partition. The statement will be applied at
# least once to each partition. It is strongly recommended that the DML
# statement should be idempotent to avoid unexpected results. For instance, it
# is potentially dangerous to run a statement such as `UPDATE table SET column =
# column + 1` as it could be run multiple times against some rows. - The
# partitions are committed automatically - there is no support for Commit or
# Rollback. If the call returns an error, or if the client issuing the
# ExecuteSql call dies, it is possible that some rows had the statement executed
# on them successfully. It is also possible that statement was never executed
# against other rows. - Partitioned DML transactions may only contain the
# execution of a single DML statement via ExecuteSql or ExecuteStreamingSql. -
# If any error is encountered during the execution of the partitioned DML
# operation (for instance, a UNIQUE INDEX violation, division by zero, or a
# value that cannot be stored due to schema constraints), then the operation is
# stopped at that point and an error is returned. It is possible that at this
# point, some partitions have been committed (or even committed multiple times),
# and other partitions have not been run at all. Given the above, Partitioned
# DML is good fit for large, database-wide, operations that are idempotent, such
# as deleting old rows from a very large table.

# # Transactions Each session can have at most one active transaction at a time (
# note that standalone reads and queries use a transaction internally and do
# count towards the one transaction limit). After the active transaction is
# completed, the session can immediately be re-used for the next transaction. It
# is not necessary to create a new session for each transaction. # Transaction
# Modes Cloud Spanner supports three transaction modes: 1. Locking read-write.
# This type of transaction is the only way to write data into Cloud Spanner.
# These transactions rely on pessimistic locking and, if necessary, two-phase
# commit. Locking read-write transactions may abort, requiring the application
# to retry. 2. Snapshot read-only. This transaction type provides guaranteed
# consistency across several reads, but does not allow writes. Snapshot read-
# only transactions can be configured to read at timestamps in the past.
# Snapshot read-only transactions do not need to be committed. 3. Partitioned
# DML. This type of transaction is used to execute a single Partitioned DML
# statement. Partitioned DML partitions the key space and runs the DML statement
# over each partition in parallel using separate, internal transactions that
# commit independently. Partitioned DML transactions do not need to be committed.
# For transactions that only read, snapshot read-only transactions provide
# simpler semantics and are almost always faster. In particular, read-only
# transactions do not take locks, so they do not conflict with read-write
# transactions. As a consequence of not taking locks, they also do not abort, so
# retry loops are not needed. Transactions may only read/write data in a single
# database. They may, however, read/write data in different tables within that
# database. ## Locking Read-Write Transactions Locking transactions may be used
# to atomically read-modify-write data anywhere in a database. This type of
# transaction is externally consistent. Clients should attempt to minimize the
# amount of time a transaction is active. Faster transactions commit with higher
# probability and cause less contention. Cloud Spanner attempts to keep read
# locks active as long as the transaction continues to do reads, and the
# transaction has not been terminated by Commit or Rollback. Long periods of
# inactivity at the client may cause Cloud Spanner to release a transaction's
# locks and abort it. Conceptually, a read-write transaction consists of zero or
# more reads or SQL statements followed by Commit. At any time before Commit,
# the client can send a Rollback request to abort the transaction. ### Semantics
# Cloud Spanner can commit the transaction if all read locks it acquired are
# still valid at commit time, and it is able to acquire write locks for all
# writes. Cloud Spanner can abort the transaction for any reason. If a commit
# attempt returns `ABORTED`, Cloud Spanner guarantees that the transaction has
# not modified any user data in Cloud Spanner. Unless the transaction commits,
# Cloud Spanner makes no guarantees about how long the transaction's locks were
# held for. It is an error to use Cloud Spanner locks for any sort of mutual
# exclusion other than between Cloud Spanner transactions themselves. ###
# Retrying Aborted Transactions When a transaction aborts, the application can
# choose to retry the whole transaction again. To maximize the chances of
# successfully committing the retry, the client should execute the retry in the
# same session as the original attempt. The original session's lock priority
# increases with each consecutive abort, meaning that each attempt has a
# slightly better chance of success than the previous. Under some circumstances (
# e.g., many transactions attempting to modify the same row(s)), a transaction
# can abort many times in a short period before successfully committing. Thus,
# it is not a good idea to cap the number of retries a transaction can attempt;
# instead, it is better to limit the total amount of wall time spent retrying. ##
# # Idle Transactions A transaction is considered idle if it has no outstanding
# reads or SQL queries and has not started a read or SQL query within the last
# 10 seconds. Idle transactions can be aborted by Cloud Spanner so that they don'
# t hold on to locks indefinitely. In that case, the commit will fail with error
# `ABORTED`. If this behavior is undesirable, periodically executing a simple
# SQL query in the transaction (e.g., `SELECT 1`) prevents the transaction from
# becoming idle. ## Snapshot Read-Only Transactions Snapshot read-only
# transactions provides a simpler method than locking read-write transactions
# for doing several consistent reads. However, this type of transaction does not
# support writes. Snapshot transactions do not take locks. Instead, they work by
# choosing a Cloud Spanner timestamp, then executing all reads at that timestamp.
# Since they do not acquire locks, they do not block concurrent read-write
# transactions. Unlike locking read-write transactions, snapshot read-only
# transactions never abort. They can fail if the chosen read timestamp is
# garbage collected; however, the default garbage collection policy is generous
# enough that most applications do not need to worry about this in practice.
# Snapshot read-only transactions do not need to call Commit or Rollback (and in
# fact are not permitted to do so). To execute a snapshot transaction, the
# client specifies a timestamp bound, which tells Cloud Spanner how to choose a
# read timestamp. The types of timestamp bound are: - Strong (the default). -
# Bounded staleness. - Exact staleness. If the Cloud Spanner database to be read
# is geographically distributed, stale read-only transactions can execute more
# quickly than strong or read-write transaction, because they are able to
# execute far from the leader replica. Each type of timestamp bound is discussed
# in detail below. ### Strong Strong reads are guaranteed to see the effects of
# all transactions that have committed before the start of the read. Furthermore,
# all rows yielded by a single read are consistent with each other -- if any
# part of the read observes a transaction, all parts of the read see the
# transaction. Strong reads are not repeatable: two consecutive strong read-only
# transactions might return inconsistent results if there are concurrent writes.
# If consistency across reads is required, the reads should be executed within a
# transaction or at an exact read timestamp. See TransactionOptions.ReadOnly.
# strong. ### Exact Staleness These timestamp bounds execute reads at a user-
# specified timestamp. Reads at a timestamp are guaranteed to see a consistent
# prefix of the global transaction history: they observe modifications done by
# all transactions with a commit timestamp <= the read timestamp, and observe
# none of the modifications done by transactions with a larger commit timestamp.
# They will block until all conflicting transactions that may be assigned commit
# timestamps <= the read timestamp have finished. The timestamp can either be
# expressed as an absolute Cloud Spanner commit timestamp or a staleness
# relative to the current time. These modes do not require a "negotiation phase"
# to pick a timestamp. As a result, they execute slightly faster than the
# equivalent boundedly stale concurrency modes. On the other hand, boundedly
# stale reads usually return fresher results. See TransactionOptions.ReadOnly.
