> In the adaptive batch scheduler, the parameter "jobmanager.
> Adaptive-batch-scheduler. Default source parallelism" configured in the
> tpc-ds test does not take effect, resulting in that only one record will be
> received in the downstream. Even if the csvtablesource has 64 parallelism, it
> will only be executed with one parallelism, resulting in poor performance of
> 99 SQL in the data reading stage
