[jira] [Created] (KAFKA-4144) Allow per stream/table timestamp extractor

Elias Levy created KAFKA-4144:
---------------------------------

             Summary: Allow per stream/table timestamp extractor
                 Key: KAFKA-4144
                 URL: https://issues.apache.org/jira/browse/KAFKA-4144
             Project: Kafka
          Issue Type: Improvement
          Components: streams
    Affects Versions: 0.10.0.1
            Reporter: Elias Levy
            Assignee: Guozhang Wang


At the moment the timestamp extractor is configured via a StreamConfig value to KafkaStreams.  That means you can only have a single timestamp extractor per app, even though you may be joining multiple streams/tables that require different timestamp extraction methods.

You should be able to specify a timestamp extractor via KStreamBuilder.stream/table, just like you can specify key and value serdes that override the StreamConfig defaults.
