> A Snapshot Cache lock needs to be implemented which should prevent the rocksdb to be opened while the lock is held.
> The idea is, the snapshot can't be opened for other purposes during snapshot compaction (note: snapshot compaction is not DB compaction). Essentially, an exclusive lock should be taken on the snapshot during the process.
