> If two tasks are competing for the same RocksDB state store provider, they
> could run into the following race condition:
>
> ||task 1||task 2||
> |load() - load version 0| |
> |commit() - committed version 1| |
> | |load() - load version 1|
> | |commit() - committed version 2|
> |getStateStoreCheckpointInfo - get checkpoint info for version 2 :(| |
> We need to ensure that checkpoint info is retrieved atomically with the
> commit() before the RocksDB instance lock is released.
