-------------------------------
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.
