Subject [jira] [Commented] (CASSANDRA-10380) SELECT count within a partition does not respect LIMIT
Date Tue, 22 Sep 2015 15:58:04 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-10380?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14902850#comment-14902850

Philip Thompson commented on CASSANDRA-10380:
---------------------------------------------

I thought this behavior was changed in CASSANDRA-7981. I must be misremembering.

> Actual: count of all rows in partition
> This manifests in 3.0, does not appear in 2.2
