Subject [jira] Commented: (CASSANDRA-1581) Filter out keys from SSTables directly
Date Wed, 06 Oct 2010 03:25:43 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-1581?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12918403#action_12918403
] 

Stu Hood commented on CASSANDRA-1581:
-------------------------------------

This is an interesting tool: what's an example usecase?

Also, it shouldn't be necessary to deserialize the row at all, so this can probably be optimized
a great deal.
