Subject [jira] [Commented] (CASSANDRA-6689) Partially Off Heap Memtables
Date Thu, 20 Mar 2014 23:11:43 GMT

Benedict commented on CASSANDRA-6689:
-------------------------------------

See my comment explaining [here|https://issues.apache.org/jira/browse/CASSANDRA-6694?focusedCommentId=13904708&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-13904708]

bq. One more nit thing, in DecoratedKey.java there is no need to mark token() and key() explicitly
"abstract", also token() is already defined in RingPosition so no need to declare it in DecoratedKey.

The latter is an artefact of merging the getToken() and token() into the same method, and
I agree. Although there's no harm in either, happy to change them.
