Why documentation always say checkpoint does not support Flink specific features like rescaling.


Hi, all

>From the latest 1.6 (or all the previous verions) documentation https://ci.apache.org/projects/flink/flink-docs-release-1.6/ops/state/checkpoints.html#difference-to-savepoints, it said "Checkpoints have a few differences from savepoints, they do not support Flink specific features like rescaling."

However, if you just take a look at RocksDB-StateBackend's code, you could see clearly that RocksDBStateBackend support rescaling from previous checkpoint. Could anyone give an explanation?
