Aha, I got it. But I also found the description of Memory state backend is
wrong in these PR, the description is `The MemoryStateBackend can be configured
to use asynchronous snapshots. While we strongly encourage the use of
asynchronous snapshots to avoid blocking pipelines, please note that this is a
new feature and currently not enabled by default.`, but I found `asynchronous
snapshots` is enabled by default, it seems like out of date, could you please
also have a look ? @StefanRRichter

> I checked that external checkpoint also supported rescale both in code and
> practice. But in the doc it still note that "do not support Flink specific
> features like rescaling."
> I am afraid whether I have missed something, if so please just close this
> issue.
