Subject [jira] [Created] (SPARK-23701) Multiple sequential watermarks are not supported
Date Fri, 16 Mar 2018 00:02:00 GMT
Jose Torres created SPARK-23701:

             Summary: Multiple sequential watermarks are not supported
                 Key: SPARK-23701
             Project: Spark
          Issue Type: Bug
          Components: Structured Streaming
    Affects Versions: 2.4.0
            Reporter: Jose Torres

In 2.3, we allowed query plans with multiple watermarks to run to enable stream-stream joins.
But we've only implemented the functionality for watermarks in parallel feeding into a join
operator. It won't work currently (and would require in-depth changes) if the watermarks are
sequential in the plan.
