Sandesh commented on APEXCORE-556:
----------------------------------
One example is in Kafka 0.9 Exactly once output operator, during recovery it
reads the tuples between 2 offsets, which is not deterministic, so having this
attribute will help. [~dtram] can you please comment on the recovery time of
file input operator?
> New operator attribute - RECOVERY_WINDOW_COUNT

> Key: APEXCORE-556
> URL: https://issues.apache.org/jira/browse/APEXCORE-556
> Project: Apache Apex Core
> Issue Type: Improvement
> Reporter: Sandesh
>
> During recovery operators need more time, so it is better to have different
> per operator attribute representing that behaviour.
> Note:
> 1. Input and output operators need to have a higher value for this attribute,
> as that is where recovery times are higher.
