Subject [jira] Created: (HBASE-2066) Perf: parallelize puts
Date Tue, 22 Dec 2009 05:10:18 GMT
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

This requires a RPC change...
