Subject [jira] Commented: (CASSANDRA-761) Binary Memtable does not invalidate cache
Date Thu, 04 Feb 2010 06:44:28 GMT

    [ 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.

> If you have RowCache turned on for your CF, and you do a BMT import, rows are not invalidated
in cache until you restart the node.
