     [ https://issues.apache.org/jira/browse/HBASE-8610?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

ramkrishna.s.vasudevan updated HBASE-8610:
------------------------------------------

    Attachment: HBASE-8610_firstcut.patch

Introduces interface for MultiWAL support.  Default implementation creates a WAL for meta and a WAL for the RS. 
TableBasedGrouper would group per table.  We can have implementation for grouping a specified number of WALs within the regions getting opened in a WAL.  I have not attached the implementation of it here in this patch.  Added testcase for DefaultGrouping and Table based grouping.  Comments and feedback welcome.
