Subject [jira] [Commented] (FLINK-4599) Add 'explain()' also to StreamTableEnvironment
Date Fri, 09 Sep 2016 08:22:20 GMT

    [ https://issues.apache.org/jira/browse/FLINK-4599?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15476313#comment-15476313

Fabian Hueske commented on FLINK-4599:

The batch explain is using the JSON output of the DataSet optimizer. There is no equivalent
component in the DataStream API (DataStream programs are deployed as they are specified).
So the implementation of the streaming explain will be different from the batch explain. The
explain plan could be created from the RelNode plan.

> Currenlty, only the BatchTableEnvironment supports the {{explain}} command for tables.
We should also support it for the StreamTableEnvironment.
