Subject [jira] Updated: (CASSANDRA-75) wire up memtable mbean
Date Mon, 13 Apr 2009 23:12:15 GMT

     [ https://issues.apache.org/jira/browse/CASSANDRA-75?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Eric Evans updated CASSANDRA-75:
--------------------------------

    Attachment: 0002-an-MBean-attribute-for-displaying-a-flush-counter.patch

This changeset adds a new attribute to the ColumnFamilyStore MBean which displays the number
of times the memtable has been "switched". This attribute (along with the newly added count
and size attributes), should prove useful in tuning thresholds.

> It would be useful in the tuning of MemtableSizeInMB and MemtableObjectCountInMillions
if the Memtable values for currentSize_ and currentObjectCount_ where exposed via JMX.
