Subject [jira] [Commented] (CASSANDRA-3077) Support TTL option to be set for column family
Date Sun, 01 Apr 2012 19:58:27 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-3077?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13243830#comment-13243830

Aleksey Vorona commented on CASSANDRA-3077:
-------------------------------------------

Technically,  this issue was created 6 month earlier than the one it is duplicate of now.
But that's not a big difference :) Also, this ticket contains two use cases, while the other
only states some optimization gain of this change. I am copying use cases to the newer bug.

> 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.
