dawidwys edited a comment on issue #9433: [FLINK-13708] [table-planner-blink] transformations should be cleared after execution in blink planner URL: https://github.com/apache/flink/pull/9433#issuecomment-522469707 Could we take a step back here and think once again when/what/why is buffered? Could we prepare such list/description in the corresponding JIRA? As far as I understood it in the bridging APIs there should be no buffering at all and the buffering should happen only in the unified one. The current state of this PR does not fix the `StreamTableEnvironment` with blink planner. You can not call `execute` on `StreamExecutionEnvironment`. Also I don't understand why should we throw exception in `explain` method. This sounds like a rather dirty hack around some design flaws.
