> Issue Type: Task

> Introducing virtual column family to RocksDB. We attach an 8-byte-Id prefix
> as column family identifier for each of the key row that is put into RocksDB.
> The encoding and decoding of the virtual column family prefix happens at the
> {{RocksDBKeyEncoder}} layer as we can pre-allocate extra 8 bytes and avoid
> additional memcpy.
