Subject [jira] [Commented] (HBASE-10648) Pluggable Memstore
Date Thu, 06 Mar 2014 01:02:00 GMT

    [ https://issues.apache.org/jira/browse/HBASE-10648?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13921802#comment-13921802
] 

Ted Yu commented on HBASE-10648:
--------------------------------

There're a few methods in MemStore interface which lack javadoc. e.g.:
{code}
+  long timeOfOldestEdit();
...
+  void getRowKeyAtOrBefore(final GetClosestRowBeforeTracker state);
{code}

> Make Memstore into an interface implementation.  Also make it pluggable by configuring
the FQCN of the impl.
> This will allow us to have different impl and optimizations in the Memstore DataStructure
and the upper layers untouched.
