> We notice that rescaling is not covered in the current state benchmark, so we'd like to introduce a benchmark for rescaling in flink-benchmark.
> The benchmark process is:
> (1) generate some states,
> (2) change the parallelism of the operator, and restore from these states generate before.
> The implementation of this benchmark is based on {{RocksIncrementalCheckpointRescalingTest}}, and *_AverageTime_* is used to measure the rescaling performance on each subtask.
>  
> And this benchmark does not conflict with `RocksIncrementalCheckpointRescalingBenchmarkTest` in 
> PR([#14893|https://github.com/apache/flink/pull/14893]). Compare with `RocksIncrementalCheckpointRescalingBenchmarkTest`, this benchmark supports testing rescaling on different state backends, and has a finer granularity.
