------------------------------------

             Summary: Introduce Join Accumulator for Wide table
                 Key: FLINK-26457
                 URL: https://issues.apache.org/jira/browse/FLINK-26457
             Project: Flink
          Issue Type: Sub-task
          Components: Table Store
            Reporter: Jingsong Lee
             Fix For: table-store-0.1.0


Consider a Join Accumulator, It will merge two records, completing the not-null fields.

It is very useful for wide tables, where two source tables join together to form a wide table.
