------------------------------------
[~waywtdcc] Can you explain your problem in more detail? As far as I know, the
source parallelism under the adaptive batch scheduler subject the following
rule:
# Kind of source can infer parallelism according to the catalog. For example,
HiveTableSource.
# Considering other sources, using the configuration
"{*}jobmanager.adaptive-batch-scheduler.default-source-parallelism{*}” to
manually configure source parallelism.
> Automatic judgment of parallelism of source

> The parallelism of the source is automatically judged. The parallelism of the
> source should not be determined by jobmanager. adaptive batch scheduler The
> default source parallelism is judged by the two configurations of
> jobmanager.adaptive batch-scheduler.min-parallelism and jobmanager.adaptive
> batch-scheduler.max-parallelism and the number of partitions
