rqlite, a distributed relational database leveraging SQLite, is gearing up for version 9.0. The primary directive: slash disk usage in half. Currently, three culprits drive disk utilization — the Raft Log, working SQLite Database, and snapshotted SQLite Database. The upcoming version will eliminate the need for duplicating SQLite data in the Raft system, working alongside snapshotting and WAL checkpointing. This innovative “Referential Snapshotting” technique will pave the way for quicker snapshotting and faster node restarts. Aiming to revolutionize efficiency and trim down disk footprint, rqlite 9.0 is on the horizon. Stay tuned for updates from Philip O’Toole.
