> Currently, there are a lot of {{TableSink}} connectors uses
> {{dataStream.addSink()}} without {{setParallelism}} explicitly. This will use
> default parallelism of the environment. However, the parallelism of input
> transformation might not be env.parallelism, for example, global aggregation
> has 1 parallelism. In this case, it will lead to data reorder, and result in
> incorrect result.
