Subject [jira] [Commented] (FLINK-6250) Distinct procTime with Rows boundaries
Date Tue, 04 Apr 2017 14:31:41 GMT

    [ https://issues.apache.org/jira/browse/FLINK-6250?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15955200#comment-15955200

Stefano Bortoli commented on FLINK-6250:
----------------------------------------

I am also fine implementing it extending the existing function. Practically it would be what
would have happened, but in another file. Currently I am trying to understand where the DISTINCT
marker gets lost as it does not arrive to the OVER aggregation function. Probably it is intercepted
in early stages of the query processing.
