Lars Hofhansl commented on HBASE-6136:
--------------------------------------
I think we can do better than that. This will fire individual Get requests at
great cost to the region server.
We should group by RegionServer and break the RegionServer portions into sub
chunks.
Or we could group by RegionServer and Region.
See HConnectionManager.HConnectionImplementation.processBatchCallback(...).
> Optimize the multi get to be executed in parallel.

> Currently the multiAction will be executed by one IPC handler thread in the
> server side. It would be more efficient to optimize the multi get
> particularly to be executed in parallel since the multiget doesn't need to
> write to the WAL.
