// # Transactions
|
|
//
|
|
//
|
|
// Each session can have at most one active transaction at a time. 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 two 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.
|
|
//
|
|
// 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][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.
|
|
//
|
|
// Reads performed within a transaction acquire locks on the data
|
|
// being read. Writes can only be done at commit time, after all reads
|
|
// have been completed.
|
|
// Conceptually, a read-write transaction consists of zero or more
|
|
// reads or SQL queries 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 (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][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 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][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 <=
|
|
// 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`.
