-------------------------------------

             Summary: Separate reader and writer thread pool in RegionServer, so that write
throughput will not be impacted when the read load is very high
                 Key: HBASE-8836
                 URL: https://issues.apache.org/jira/browse/HBASE-8836
             Project: HBase
          Issue Type: New Feature
          Components: Performance, regionserver
    Affects Versions: 0.94.8
            Reporter: Tianying Chang
            Assignee: Tianying Chang
             Fix For: 0.94.8


We found that when the read load on a specific RS is high, the write throughput also get impacted
dramatically, and even cause write data loss sometimes. We want to prioritize the write by
putting them in a separate queue from the read request, so that slower read will not make
fast write wait nu-necessarily long.
