Details

    • New Feature
    • Status: Resolved
    • Major
    • Resolution: Fixed
    • None
    • 3.0.0-alpha-1, 2.1.0
    • Replication
    • None
    • Now in replication we can make sure the order of pushing logs is same as the order of requests from client. Set the serial flag to true for a replication peer to enable this feature.

    Description

      When implementing HBASE-9465 we added two new families to meta table, one is rep meta and the other is rep_position. In general I think rep_meta is OK to put into meta table since it records the open and close sequence id for a region, but for rep_position, I think it should be put into another system table instead of meta table.

      This should be done before we finally release 2.0.0 or 1.5.0.
