The RocksDBCheckpointMetadata persists the metadata for each committed batch in JSON format. The object contains all RocksDB file names and the number of total keys.
The metadata binds closely with the directory structure of RocksDBFileManager, as described in the design doc - [Directory Structure and Format for Files stored in DFS|https://docs.google.com/document/d/10wVGaUorgPt4iVe4phunAcjU924fa3-_Kf29-2nxH6Y/edit#heading=h.zgvw85ijoz2]
