Subject [jira] [Commented] (APEXCORE-556) New operator attribute - RECOVERY_WINDOW_COUNT
Date Wed, 12 Oct 2016 16:13:20 GMT

    [ https://issues.apache.org/jira/browse/APEXCORE-556?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15569136#comment-15569136

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?

> 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.
