Subject [jira] [Commented] (CASSANDRA-3077) Support TTL option to be set for column family
Date Tue, 27 Mar 2012 14:28:31 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-3077?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13239497#comment-13239497

Leonardo Stern commented on CASSANDRA-3077:
-------------------------------------------

Agree with the default value. Default TTF would be very helpfull in Map/Reduce scenarios where
you dont have direct control of TTL (IE: hive)

> Use case: I want one of my CFs not to store any data older than two months. It is a "notifications"
CF which is of no interest to user.
> Currently I am setting TTL with each insert in the CF, but since it is a constant it
makes sense to me to have it configured in CF definition to apply automatically to all rows
in the CF.
