Perf: parallelize puts
----------------------
Key: HBASE-2066
URL: https://issues.apache.org/jira/browse/HBASE-2066
Project: Hadoop HBase
Issue Type: Bug
Affects Versions: 0.20.2
Reporter: ryan rawson
Fix For: 0.20.3, 0.21.0
Right now with large region count tables, the write buffer is not efficient.
This is because we issue potentially N RPCs, where N is the # of regions in the
table. When N gets large (lets say 1200+) things become sloowwwww.
Instead if we batch things up using a different RPC and use thread pools, we
could see higher performance!
This requires a RPC change...
