Flink - SQL can separate a certain parallelism of operator node configuration?

Can flink-sql configure the parallelism of an operator node independently?

Accept answer 1:

No, if there is parameter support in the source/sink with() of the connector, you can configure it through parameters. If you don't have it, you have to change the connector support (this answer is organized from [③group] Apache Flink China community)
