Subject [GitHub] flink pull request: [FLINK-1967] Introduce (Event)time in Streamin...

    I thought about how we could change it so that the Watermarks are transmitted "in-band"
with the stream records. This would require the StreamRecordSerializer to handle different
types of records (copy, deserialize, serialize, etc.). For this, I would propose to remove
knowledge about the StreamRecord serializer from all layers except the StreamTask layer, because
it does not work like a normal TypeSerializer anymore.
