[jira] [Comment Edited] (CASSANDRA-18352) Add Option to Timebox write timestamps

    [ https://issues.apache.org/jira/browse/CASSANDRA-18352?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17706117#comment-17706117 ]

I can see at least a few dtest failures that a rebase would fix, though I hate to ask for that while circle is in its current shape.

> In several cases it is desirable to have client provided timestamps generated at the application-level. This can be error prone, however. In particular, applications can choose timestamps that may be nonsensical for a given application. One dangerous manifestation of this is the "doomstone" (a tombstone far in the future of any realistic write). This feature would allow either operators or users to specify a minimum and maximum timebound of "reasonable" timestamps. The default would be negative infinity, positive infinity to maintain backwards compatibility. Writes that are USING TIMESTAMP with a timestamp outside of the timebox will see an exception.
