shardedWriteTransaction

SProcCall.WriteTransaction shardedWriteTransaction

Defines how sharded writes will be handled. If set to SProcCall.WriteTransaction.NONE, no transaction context will be created. If set to SProcCall.WriteTransaction.ONE_PHASE, all errors during the sproc call will be rolled back. If set to SProcCall.WriteTransaction.TWO_PHASE, all errors during sproc call and "prepare transaction" are rolled back. In the last case, the Postgres instance must be configured to manage 2-phase-commits (XA).
