Overview

A transaction.

Instance Attribute Summary

• #id ⇒ ::String

  id may be used to identify the transaction in subsequent Read, ExecuteSql, Commit, or Rollback calls.

• #precommit_token ⇒ ::Google::Cloud::Spanner::V1::MultiplexedSessionPrecommitToken

  A precommit token is included in the response of a BeginTransaction request if the read-write transaction is on a multiplexed session and a mutation_key was specified in the BeginTransaction.

• #read_timestamp ⇒ ::Google::Protobuf::Timestamp

  For snapshot read-only transactions, the read timestamp chosen for the transaction.

Instance Attribute Details

#id ⇒ ::String

Returns id may be used to identify the transaction in subsequent Read, ExecuteSql, Commit, or Rollback calls.

Single-use read-only transactions do not have IDs, because single-use transactions do not support multiple requests.

Returns:

• (::String) —

  id may be used to identify the transaction in subsequent Read, ExecuteSql, Commit, or Rollback calls.

  Single-use read-only transactions do not have IDs, because single-use transactions do not support multiple requests.

#precommit_token ⇒ ::Google::Cloud::Spanner::V1::MultiplexedSessionPrecommitToken

Returns A precommit token is included in the response of a BeginTransaction request if the read-write transaction is on a multiplexed session and a mutation_key was specified in the BeginTransaction. The precommit token with the highest sequence number from this transaction attempt should be passed to the Commit request for this transaction.

Returns:

• (::Google::Cloud::Spanner::V1::MultiplexedSessionPrecommitToken) —

  A precommit token is included in the response of a BeginTransaction request if the read-write transaction is on a multiplexed session and a mutation_key was specified in the BeginTransaction. The precommit token with the highest sequence number from this transaction attempt should be passed to the Commit request for this transaction.

#read_timestamp ⇒ ::Google::Protobuf::Timestamp

Returns For snapshot read-only transactions, the read timestamp chosen for the transaction. Not returned by default: see TransactionOptions.ReadOnly.return_read_timestamp.

A timestamp in RFC3339 UTC \"Zulu\" format, accurate to nanoseconds. Example: "2014-10-02T15:01:23.045123456Z".
