Subject [GitHub] flink issue #4633: [FLINK-7564] [table] Fix Watermark semantics in RowTimeUn...
Date Tue, 05 Sep 2017 09:19:02 GMT
Github user fhueske commented on the issue:

    Hi, processing time does not have the concept of watermarks. Watermarks are used to indicate
progress on a stream with records that have out-of-order timestamps. Processing time timestamps
are never out-of-order, so there is no need to consolidate the logic.
