Subject [jira] [Commented] (APEXCORE-556) New operator attribute - RECOVERY_WINDOW_COUNT
Date Wed, 12 Oct 2016 15:37:22 GMT

    [ https://issues.apache.org/jira/browse/APEXCORE-556?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15569056#comment-15569056

Thomas Weise commented on APEXCORE-556:
---------------------------------------

The assumption that operators need (significantly) more time during recovery seems problematic.
This may be a problem with the operator. Blocking the operator in setup for a long time causes
the entire pipeline it is part of to block.  Please provide examples. 

Such operator behavior does not only affect recovery after failures, but also redeploy after
dynamic plan changes.

> 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.
