Arvind Prabhakar commented on FLUME-1139:
-----------------------------------------
@Hari - the exposed transaction is to enable multi-event put/take semantics.
Any optimization needed to facilitate this exchange is internal detail of the
channel. I do not think it makes sense to expose the batch semantics at the
channel level.

> Adding this will help improve performance of channels that use persistent
> storage to store events, since this will reduce the number of output stream
> flushes - especially if the channel buffers events in memory like recoverable
> memory channel.
