Subject [jira] Commented: (CASSANDRA-699) Add (optional) expiration time for column
Date Tue, 06 Apr 2010 16:13:33 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-699?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12854039#action_12854039
] 

Jonathan Ellis commented on CASSANDRA-699:
------------------------------------------

> Maybe we could then return simply the timestamp

that would make the most sense, yes.

as long as we're sure the rest of the code can handle isMarkedForDelete being true, while
the client has not yet set a deletion time (which getMarkedForDeleteAt would return).

> An expiring column could be deleted the usual way, or am I missing something ?

isMarkedForDelete only checks localExpirationTime, not a deletion explicitly set by client.

> An expired column would act much like a 'markedForDelete' one.
