Turning SQLite into a distributed database

mvSQLite is a distributed database that maintains SQLite compatibility while offering enhanced scalability and stricter consistency guarantees than ACID (Atomicity, Consistency, Isolation, Durability) properties. It decouples SQLite’s storage layer onto FoundationDB, enabling features like read and write scalability, automatic sharding, external consistency, synchronous replication, and point-in-time reads. mvSQLite aims to be a drop-in replacement for SQLite, requiring minimal changes to existing applications. It provides a transparent distribution layer that handles concurrent writes, ensuring serializability and mitigating conflicts. The system employs efficient data encoding techniques and relies on FoundationDB’s transactional mechanisms for ACID properties, avoiding local journals. With beta software status, mvSQLite comes with a warning, but offers robust backup solutions, making it a compelling option for distributed databases.
