---------------------------------------
Resolution: Later
> Allow bulk load via streaming to complete 'transactionally'
> -----------------------------------------------------------
>
> Key: CASSANDRA-2900
> URL: https://issues.apache.org/jira/browse/CASSANDRA-2900
> Project: Cassandra
> Issue Type: New Feature
> Components: Tools
> Reporter: Stu Hood
> Priority: Minor
>
> It would be great if the bulk loader had the ability to "cancel" any streams
> that had completed if other streams fail, to narrow the window where a job
> could be half-completed. This is mostly only a problem for counter bulk loads
> or cases where the bulk load timestamps do not allow for idempotency.
> One possible way to implement this would be to have streaming (optionally?)
> add streamed files to a pool out-of-reach of compaction, which would allow
> you to cancel or finalize them depending on the success of the entire bulk
> load.
