["Amol Fasale (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CASSANDRA-2103?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13961035#comment-13961035 ] 

Amol Fasale commented on CASSANDRA-2103:
----------------------------------------

Agreed with Nikolay, counters should have TTL values, but only once insertable, should not be updatable (Only when initializing the counters). Next time whenever counters increments, should ignore the TTL.

Usecase like, when we are maintaining a realtime counters, like daily page views, next day these becomes useless, should not have any point storing keeping this unnecessary data and increasing overhead.
