Gary Helmling updated HBASE-2002:
---------------------------------
Attachment: HBASE-2002_final.patch
Patch for commit from the HBASE-2321 & HBASE-2002 patch on review board.
The only changes from the review board patch are a merge up to the latest trunk
for a clean diff, some whitespace and line wrapping fixes, and bumping the RPC
version number to 28, since the connection header now contains the protocol
interface name.

> "High-level call interface for clients. Unlike RPC, calls addressed to rows
> or ranges of rows. Coprocessor client library resolves to actual locations.
> Calls across multiple rows automatically split into multiple parallelized
> RPCs"
> Generic multicall RPC facility which incorporates this and
> multiget/multiput/multidelete and parallel scanners.
> Group and batch RPCs by region server. Track and retry outstanding RPCs. Ride
> over region relocations.
> Support addressing by explicit region identifier or by row key or row key
> range.
> Include a facility for merging results client side.
