public sealed class MultiplexedSessionPrecommitToken : IMessage<MultiplexedSessionPrecommitToken>, IEquatable<MultiplexedSessionPrecommitToken>, IDeepCloneable<MultiplexedSessionPrecommitToken>, IBufferMessage, IMessage
Reference documentation and code samples for the Google Cloud Spanner v1 API class MultiplexedSessionPrecommitToken.
When a read-write transaction is executed on a multiplexed session,
this precommit token is sent back to the client
as a part of the [Transaction] message in the BeginTransaction response and
also as a part of the [ResultSet] and [PartialResultSet] responses.
An incrementing seq number is generated on every precommit token
that is returned. Clients should remember the precommit token with the
highest sequence number from the current transaction attempt.
