[jira] Commented: (CASSANDRA-761) Binary Memtable does not
invalidate cache
[ https://issues.apache.org/jira/browse/CASSANDRA-761?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12829479#action_12829479 ]
Jonathan Ellis commented on CASSANDRA-761:
------------------------------------------
... cache invalidation at BMT insertion time as shown in this patch actually won't work; a read could still pull the old version into the cache again, since BMT contents are not "live" to readers.
you'll need to add "nodetool invalidate" instead.
