Description: The maximum amount of time, in milliseconds, that a messaging bridge instance waits before sending a batch of messages in one transaction, regardless of whether the Batch Size has been reached or not. Only applies to a messaging bridge instance forwarding messages in synchronous mode and has a QOS (quality of service) that requires two-phase transactions. The default value of -1 indicates that the bridge instance waits until the number of messages reaches the Batch Size before it completes a transaction.
