The article explains how rqlite, a distributed relational database built on SQLite and Raft, takes control of SQLite's Write-Ahead Log (WAL) to ensure reliable replication and snapshotting. It details the challenges of integrating SQLite's WAL management with Raft's consensus requirements and how rqlite's custom approach improves upon the default HashiCorp Raft snapshotting mechanism. The technical deep dive provides valuable insights into distributed systems design and SQLite internals.
Background
rqlite is an open-source, distributed relational database that uses SQLite as its storage engine and Raft consensus algorithm for replication. The integration of SQLite's WAL with Raft's requirements presents unique technical challenges in distributed database design.
