Subject [jira] [Created] (HBASE-11511) Write flush events to WAL
Date Mon, 14 Jul 2014 18:16:08 GMT
Enis Soztutar created HBASE-11511:

             Summary: Write flush events to WAL
                 Key: HBASE-11511
                 URL: https://issues.apache.org/jira/browse/HBASE-11511
             Project: HBase
          Issue Type: Sub-task
            Reporter: Enis Soztutar
            Assignee: Enis Soztutar

We used to write COMPLETE_FLUSH event to WAL until it got removed in 0.96 in issue HBASE-7329.

For secondary region replicas, it is important to share the data files with the primary region.
So we should reintroduce the flush wal markers so that the secondary region replicas can pick
up the newly flushed files from the WAL and start serving data from those. 

A design doc which explains the context a bit better can be found in HBASE-11183.
