Yufei Zhang commented on FLINK-25582:
-------------------------------------
I currently use `table.exec.resource.default-parallelism` to set the sql source
parallelism. But still it would be nice to set the source parallelism
explicitly.
> flink sql kafka source cannot special custom parallelism

> when use flink sql api, all operator have same parallelism, but in some times
> we want specify the source / sink parallelism for kafka source, i noticed the
> kafka sink already have parameter "sink.parallelism" to specify the sink
> parallelism, but kafka source no, so we want flink sql api, have a parameter
> to specify the kafka source parallelism like sink.
