Subject [jira] Commented: (CASSANDRA-76) Don't rely on flushkey_ special value to force flush
Date Tue, 05 May 2009 15:58:30 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-76?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12706080#action_12706080
] 

Eric Evans commented on CASSANDRA-76:
-------------------------------------

01-eliminate-special-flush-key.txt (supercedes 0001-trigger-flushes-directly-without-use-of-flushKey.txt)

This changeset abstracts the logic for placing a flush on the queue into a new method, Memtable.enqueueFlush.
enqueueFlush is called from both forceflush and put (when a threshold is exceeded), without
the need to apply a special flushKey.

02-add-force-flush-to-mbean.txt 

This patch adds ColumnFamilyStore.forceflush to the mbean so that it can be activate through
the management agent.

> We can force flush programatically w/o needing this workaround.
