[jira] [Created] (FLINK-28214) ArrayDataSerializer can not be reused to copy customized type of array data

Yi Tang created FLINK-28214:
-------------------------------

             Summary: ArrayDataSerializer can not be reused to copy customized type of array data 
                 Key: FLINK-28214
                 URL: https://issues.apache.org/jira/browse/FLINK-28214
             Project: Flink
          Issue Type: Improvement
            Reporter: Yi Tang


In FLINK-25238, we fix the ArrayDataSerializer to support copying customized type of array data with similar way in MapDataSerializer.

The MapDataSerializer#toBinaryMap always contains copy semantics implicitly
but ArrayDataSerializer#toBinaryArray not.
So the returned value of ArrayDataSerializer#toBinaryArray will be covered by new copied data.

We should always copy from the returned value of ArrayDataSerializer#toBinaryArray in ArrayDataSerializer#copy explicitly.
