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][google.spanner.v1.Spanner.Commit] or - [Rollback][google.spanner.v1.Spanner.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][google.spanner.v1.Spanner.Commit]. At any time before - [Commit][google.spanner.v1.Spanner.Commit], the client can send a - [Rollback][google.spanner.v1.Spanner.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 (for example, 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 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. If an idle - transaction is aborted, the commit will fail with error ``ABORTED``. - - If this behavior is undesirable, periodically executing a simple SQL - query in the transaction (for example, ``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][google.spanner.v1.Spanner.Commit] or - [Rollback][google.spanner.v1.Spanner.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 transactions, 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. - - Queries on change streams (see below for more details) must also - specify the strong read timestamp bound. - - See - [TransactionOptions.ReadOnly.strong][google.spanner.v1.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 less than or equal to 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][google.spanner.v1.TransactionOptions.ReadOnly.read_timestamp] - and - [TransactionOptions.ReadOnly.exact_staleness][google.spanner.v1.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][google.spanner.v1.TransactionOptions.ReadOnly.max_staleness] - and - [TransactionOptions.ReadOnly.min_read_timestamp][google.spanner.v1.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``. - - You can configure and extend the ``VERSION_RETENTION_PERIOD`` of a - database up to a period as long as one week, which allows Cloud - Spanner to perform reads up to one week in the past. - - Querying change Streams: - - A Change Stream is a schema object that can be configured to watch - data changes on the entire database, a set of tables, or a set of - columns in a database. - - When a change stream is created, Spanner automatically defines a - corresponding SQL Table-Valued Function (TVF) that can be used to - query the change records in the associated change stream using the - ExecuteStreamingSql API. The name of the TVF for a change stream is - generated from the name of the change stream: - READ_. - - All queries on change stream TVFs must be executed using the - ExecuteStreamingSql API with a single-use read-only transaction with - a strong read-only timestamp_bound. The change stream TVF allows - users to specify the start_timestamp and end_timestamp for the time - range of interest. All change records within the retention period is - accessible using the strong read-only timestamp_bound. All other - TransactionOptions are invalid for change stream queries. - - In addition, if TransactionOptions.read_only.return_read_timestamp - is set to true, a special value of 2^63 - 2 will be returned in the - [Transaction][google.spanner.v1.Transaction] message that describes - the transaction, instead of a valid read timestamp. This special - value should be discarded and not used for any subsequent queries. - - Please see https://cloud.google.com/spanner/docs/change-streams for - more details on how to query the change stream TVFs. - - 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. + r"""Options to use for transactions.
