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.
> Support TTL option to be set for column family

> Key: CASSANDRA-3077
> URL: https://issues.apache.org/jira/browse/CASSANDRA-3077
> Project: Cassandra
> Issue Type: Wish
> Components: Core
> Affects Versions: 0.8.4
> Reporter: Aleksey Vorona
> Priority: Minor
>
> 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.
