I am currently implementing the use `paralleism.default` instread of the
`execution.batch.adaptive.auto-parallelism.default-source-parallelism.` in
[pr-22555|[https://github.com/apache/flink/pull/22555|https://github.com/apache/flink/pull/22555)]]

> Currently, the sources need to set
> {{execution.batch.adaptive.auto-parallelism.default-source-parallelism }} in
> the adaptive batch scheduler mode, otherwise, the source parallelism is only
> 1 by default. A better solution might be set as the default execution
> parallelism if no user configured.
