Subject [jira] [Updated] (HBASE-3526) Tables with TTL should be able to prune memstore w/o flushing
Date Wed, 23 Mar 2011 01:42:05 GMT

     [ https://issues.apache.org/jira/browse/HBASE-3526?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

stack updated HBASE-3526:
-------------------------

    Fix Version/s:     (was: 0.90.2)
                   0.92.0

Moving to 0.92.0.... too substantial for a patch release (Ryan would be the first to say so).

> If you have a table with TTL, the memstore will grow until it hits flush size, at which
point the flush code will prune the KVs going to hfile. If you have a small TTL, it may not
be necessary to flush, since pruning data in memory would ensure that we never grow too big.
