[jira] Commented: (CASSANDRA-856) Binary Memtable interface writes the same data after each flush.

["Jonathan Ellis (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CASSANDRA-856?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12842359#action_12842359 ] 

Jonathan Ellis commented on CASSANDRA-856:
------------------------------------------

this is because the flush code calls switch() on the normal memtable, meaning flush and replace w/ a new one, but only flush() on the binary one, not replacing it w/ a new one

> Binary Memtable interface writes the same data after each flush.

> Subsequent flushes to an a Binary Memtable that has not been modified since the last flush has ghost data written out to the data directory. I've verified that the md5sum of the all the subsequent files are identical.
