Properties

CommitDelay

public TimeSpan? CommitDelay { get; }

The maximum amount of time the commit may be delayed server side for batching with other commits. The bigger the delay, the better the throughput (QPS), but at the expense of commit latency. If set to Zero, commit batching is disabled. May be null, in which case commits will continue to be batched as they had been before this configuration option was made available to Spanner API consumers. May be set to any value between Zero and 500ms.

Property Value

`TimeSpan`

Default

public static AmbientTransactionOptions Default { get; }

TimestampBound

public TimestampBound TimestampBound { get; }

TransactionId

public TransactionId TransactionId { get; }

The transaction ID of an active read-only transaction to use for the ambient transaction. May be null. At most, one of TimestampBound and TransactionId may be set. If none of TimestampBound and TransactionId are set, the ambient transaction will be a read-write transaction.
