[jboss-jira] [JBoss JIRA] (JGRP-2225) Allow for sending of message batches in JChannel and protocols

[Bela Ban (JIRA)]

    [ https://issues.jboss.org/browse/JGRP-2225?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13481597#comment-13481597 ] 

Bela Ban commented on JGRP-2225:
--------------------------------

We could check at initialization time (setting a flag) whether a protocol implements {{down(Message)}} but not {{down(MessageBatch)}} and throw an exception (bad!) or translate the batched {{down()}} method into multiple unbatches ones.
However, this still means we have to implement the batched {{down()}} method for almost all protocols, plus a single (e.g. new) protocol not doing this would break the batched down-chain...

I'm therefore currently leaning toward closing this JIRA...

> Currently, we receive messages and message batches, but we're not able to _send_ message batches. Investigate adding a {{JChannel.send(MessageBatch)}} and {{Protocol.down(MessageBatch)}}.
> The use case is that if we want to send 10 messages to the same destination, we currently send 10 messages. Because they're on the same thread, they;re _not_ likely to end up in the same batch.
> Sending a message batch down the stack ensures that all messages end up in the same message batch (unless the max bundle size is exceeded).
