[jira] [Created] (CAMEL-16039) Reinstate Batch JMS Processing

Brad Harvey created CAMEL-16039:
-----------------------------------

             Summary: Reinstate Batch JMS Processing
                 Key: CAMEL-16039
                 URL: https://issues.apache.org/jira/browse/CAMEL-16039
             Project: Camel
          Issue Type: New Feature
          Components: camel-sjms
    Affects Versions: 3.8.0
            Reporter: Brad Harvey


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.
