NameDescriptionVersion
Replay after Replication Group Message ID
Applications can now replay messages following the message-ID of the last message which they successfully-processed.
The feature uses "replication group message ID" which uniquely identifies messages within an HA group and Replication/DR group of brokers. The broker includes this ID in all guaranteed messages it delivers to the consumer. Consuming applications can extract and save this ID along with the message payload, and then use it later to initiate a replay.
This is a more "fine-grained" way to start a replay than from date-and-time, and is ideal in cases where the last message-ID successfully processed is known by the application (e.g. recovery from a database crash).
To initiate replay after message-ID from an application, both the PubSub+ Event Broker and PubSub+ Event API must be upgraded. The following versions introduce support for replay after message-ID:
Broker:
* PubSub+ Event Broker version 9.9.0
Messaging API:
* PubSub+ Messaging API for Java version 10.11.0
* PubSub+ Messaging API for C version 7.18.0
* PubSub+ Messaging API for JavaRTO version 7.18.0
* PubSub+ Messaging API for .NET version 10.12.0
* PubSub+ Messaging API for JavaScript version 10.7.0
