> A snapshot handle present inside a snapshot cache can be reused. Once the
> snapshot content lock is taken a rocksdb handle could be still present in the
> snapshot cache and after the atomic switch the old db handle could still get
> reused for writes thus missing potential writes on the newly switched db.
> Hence while performing the move directory a snapshot cache lock should be
> acquired to ensure the next db handle would always be from the new rocksdb
> handle.
