Andrew Purtell updated HBASE-8836: ---------------------------------- Fix Version/s: (was: 0.98.0) Moving out of 0.98 > 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 > Attachments: HBase-8836-QosAnotation.patch, > Hbase-8836-perfNumber.pdf, hbase-8836.patch, threadPool-write-NoWAL.png, > threadPool-write-WithWAL.png > > > 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. -- This message was sent by Atlassian JIRA (v6.1#6144)
