Description

Please provide a means of receiving multiple JMS messages as a batch in a single transaction.

Our use case is to exchange JMS messages in order, quickly, with at least once delivery guarantee, but over a link with 10 to 15 ms latency.  Processing multiple JMS messages in a single transaction is the way to meet this requirement as it greatly reduces the chatter over the wire:

• For sending, we use the normal JMS component with a loop (using <split/>) inside the transaction.
• For receiving (in 3.4.5) we use sjms-batch with an aggregation strategy.  Example
  • from sjms-batch:myqueue?aggregationStrategy=#groupedBodyAggregationStrategy&completionSize=300&asyncStartListener=true&keepAliveDelay=5000

The sjms-batch component was removed as part of the overhaul of sjms, but there appears to be no alternative to the functionality it provided.
