Subject [jira] [Commented] (FLINK-11936) Remove AuxiliaryConverter pull-in from calcite and fix auxiliary converter issue.
Date Mon, 15 Apr 2019 10:49:00 GMT

    [ https://issues.apache.org/jira/browse/FLINK-11936?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16817853#comment-16817853

Timo Walther commented on FLINK-11936:
--------------------------------------

Making the AuxiliaryConverter pluggable in Calcite would be nice solution. Otherwise we could
also think about introducing some early conversion/normalization rule to convert to what we
need. Aligning our windows with Calcite's windows might not be possible as we have slightly
different semantics because of watermarks (window end is always {{watermark-1}}?).

> AuxiliaryConverter was pulled inĀ FLINK-6409. SinceĀ CALCITE-1761 has been fixed, we
should sync back with the calcite version.
> After a quick glance, I think it is not so simple to just delete the class so I opened
a follow up Jira on this issue.
