Subject [jira] Commented: (CASSANDRA-699) Add (optional) expiration time for column
Date Mon, 18 Jan 2010 13:11:54 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-699?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12801772#action_12801772
] 

Sylvain Lebresne commented on CASSANDRA-699:
--------------------------------------------

Right now, if someone provide a ttl <=0, the code just do as if they had provided no ttl.
Not sure it's smart. Maybe it would be better to either
  * not check the ttl and let people deal with what happens
  * throw an InvalideRequestException

Any preferences ?

> Allow to attach an expiration time to a column. 
> An expired column would act much like a 'markedForDelete' one.
