Jacques Nadeau commented on DRILL-641:
--------------------------------------
as part of this, we need to remove the cleanup method from the recordbatch
interface. each operator should know when it is done with memory and release
rather than waiting for someone else to tell it.
> Better semantic and handling for kill()
> ---------------------------------------

> Key: DRILL-641
> URL: https://issues.apache.org/jira/browse/DRILL-641
> Project: Apache Drill
> Issue Type: Improvement
> Reporter: Mehant Baid
>
> Currently when an operator invokes kill(), only the upstream operators within
> that fragment get terminated. This causes problems if the upstream operator
> in a different fragment is still continuously producing batches, and it then
> becomes the responsibility of the operator to drain all the batches even
> though a kill was issued.
> While dealing with plans with multiple fragments we would need to inform the
> sender that a kill has been invoked. It would then be the responsibility of
> the sender to not push any more batches to the corresponding receiver.
