[jira] [Created] (FLINK-8650) Add tests and documentation for WINDOW clause

Timo Walther created FLINK-8650:
-----------------------------------

             Summary: Add tests and documentation for WINDOW clause
                 Key: FLINK-8650
                 URL: https://issues.apache.org/jira/browse/FLINK-8650
             Project: Flink
          Issue Type: Improvement
          Components: Table API &amp; SQL
            Reporter: Timo Walther


We support queries with a {{WINDOW}} clause like:

{code}
SELECT a, SUM(c) OVER w, MIN(c) OVER w FROM MyTable WINDOW w AS (PARTITION BY a ORDER BY proctime ROWS BETWEEN 4 PRECEDING AND CURRENT ROW)
{code}

But this is neither documented nor tested.
