Subject [jira] [Created] (FLINK-4367) Offer separate API for watermark generation and timestamp extraction
Date Wed, 10 Aug 2016 14:49:20 GMT
Robert Metzger created FLINK-4367:
-------------------------------------

             Summary: Offer separate API for watermark generation and timestamp extraction
                 Key: FLINK-4367
                 URL: https://issues.apache.org/jira/browse/FLINK-4367
             Project: Flink
          Issue Type: Sub-task
          Components: DataStream API
    Affects Versions: 1.1.0
            Reporter: Robert Metzger
             Fix For: 2.0.0


Right now, the {{AssignerWithPunctuatedWatermarks}} and {{AssignerWithPeriodicWatermarks}}
interfaces also require implementing a {{TimestampAssigner}}.

For cases where the source emits records with timestamps, its not necessary to extract timestamps
again from the records, we just want to generate watermarks.
