[jira] [Created] (FLINK-20281) Window aggregation supports changelog stream input

Jark Wu created FLINK-20281:
-------------------------------

             Summary: Window aggregation supports changelog stream input
                 Key: FLINK-20281
                 URL: https://issues.apache.org/jira/browse/FLINK-20281
             Project: Flink
          Issue Type: New Feature
          Components: Table SQL / Planner, Table SQL / Runtime
            Reporter: Jark Wu


Currently, window aggregation doesn't support to consume a changelog stream. This makes it impossible to do a window aggregation on changelog sources (e.g. Kafka with Debezium format, or upsert-kafka, or mysql-cdc).
