MotherDuck introduces Differential Storage, a new solution extending DuckDB to operate as a collaborative data warehouse. This innovation allows for efficient data sharing, zero-copy clone, snapshots, branching, and time travel. Differential Storage solves scalability issues by providing a copy-on-write storage solution. By representing the database state as a series of immutable snapshot layer files, MotherDuck can implement collaboration and backup/restore features quickly and cost-effectively. Zero-copy snapshots and forks, time travel capabilities, improved cacheability, and data tiering are among the new features unlocked by Differential Storage. MotherDuck encourages users to explore the new capabilities and start quacking with their supercharged analytics experience.
