Purpose of the change
Add new option
scan.parallelismsupport for JDBC connector.Part of FLINK-33261 FLIP-367: Support Setting Parallelism for Table/SQL Sources
The change is not backward compatible for versions <= 1.18.
InputFormatProvider of(InputFormat<RowData, ?> inputFormat, @Nullable Integer sourceParallelism)was added in Flink 1.19. Therefore, we need to wait with this change until JDBC connector is no longer supporting Flink 1.18.
