---------------------------------
Summary: The default source parallelism configuration in adaptive
batch scheduling does not take effect
Key: FLINK-26579
URL: https://issues.apache.org/jira/browse/FLINK-26579
Project: Flink
Issue Type: Bug
Components: API / DataStream
Affects Versions: 1.15.0
Reporter: kangTwang
Fix For: 1.15.0
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
