[jira] [Commented] (BOOKKEEPER-406) Provide support in hedwig to batch multiple messages

["Ivan Kelly (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/BOOKKEEPER-406?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13477788#comment-13477788 ] 

Ivan Kelly commented on BOOKKEEPER-406:
---------------------------------------

I don't think we should introduce any transactional guarantee for this feature yet. It could be added after, but doing so now complicate things and I think batching and transactions can be cleanly separated. 

[~i0exception] How do you envisage the batching API for publishes?

For message delivery we would simply have to modify the PubSubResponse to have repeated messages rather than a single.

> In the current implementation, each message is sent as a separate PubSubResponse. Also, a PubSubRequest sends only one message per request. This introduces a lot of overhead if the message body is small. 
> Hedwig should provide a batched request API where messages can be consumed or published in batches.
