Subject [jira] [Commented] (FLINK-4565) Support for SQL IN operator
Date Wed, 23 Nov 2016 15:38:59 GMT

    [ https://issues.apache.org/jira/browse/FLINK-4565?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15690440#comment-15690440

Fabian Hueske commented on FLINK-4565:
--------------------------------------

Hi [~nvasilishin], sorry for the late reply.

I would suggest to open a pull request for the first two cases ({{IN (list-of-literals)}})
and address the {{IN (table)}} case later. Smaller pull requests are easier to handle and
allow for faster review cycles.

The {{IN (table)}} case is also a bit more complex because we need to think about the API,
i.e., how to integrate the {{table: Table}} into the expressions of {{where()}}.

> It seems that Flink SQL supports the uncorrelated sub-query IN operator. But it should
also be available in the Table API and tested.
