@StefanRRichter Do you think we should try to figure out which SST files
have been compacted and exclude them from recovery?
> Implement incremental checkpointing in RocksDBStateBackend

> {{RocksDBStateBackend}} is well suited for incremental checkpointing because
> RocksDB is base on LSM trees, which record updates in new sst files and all
> sst files are immutable. By only materializing those new sst files, we can
> significantly improve the performance of checkpointing.
