> Changle log does not work correctly with InMemory store. If you kill a job
> and start it again, it will not read from the beginning of the change log and
> bootstrap the state. Instead it will read from the newest offset.
> The reason for this bug is that the OFFSET file will be created even if the
> RocksDB store is not used. When a job is restated it checks if an OFFSET file
> exist, and if it does it will use those offsets as the offset to read from
> the change log. However, for an InMemory store, the state has to be rebuilt
> form the beginning since there is not snapshot on the disk, even though the
> OFFSET file is there.
