> Currently, when OM creates a file/directory, it checks the absence of all
> prefix paths of the key in its RocksDB. Since we don't care about the
> deserialization of the actual value, we should use the isExist API added in
> org.apache.hadoop.hdds.utils.db.Table which internally uses the more
> performant keyMayExist API of RocksDB.
