Subject [jira] [Commented] (FLINK-6959) Add documentation for SQL OVER windows
Date Wed, 21 Jun 2017 07:45:00 GMT

    [ https://issues.apache.org/jira/browse/FLINK-6959?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16057103#comment-16057103

Fabian Hueske commented on FLINK-6959:
--------------------------------------

I don't think we need to add a specific section to the documentation. This is standard SQL
syntax and semantics. 
Group windows have their own section beause the window functions (TUMBLE, HOP, etc) are Calcite
specific an part of the SQL standard.

We could extend the OVER window entry in the Aggregation Operations and be more specific about
the limitations though.
