Subject [jira] [Commented] (HBASE-6374) [89-fb] Unify the multi-put/get/delete path so there is only one call to each RS, instead of one call per region

Amitanand Aiyer commented on HBASE-6374:
----------------------------------------

@Lars, I think trunk has the batch primitive; which 0.89-fb does not. Hence the diff. I do
not think this is something that trunk is lacking.

> This is a feature similar to the batch feature in trunk. 
> We have optimisation for the put path where we batch puts by the regionserver, but for
gets and deletes we do batching only per hregion. So, if there are 20 regions on a regionserver,
we would be doing 20 RPC when we can potentially batch them together in 1 call.
