Taking Control of the SQLite WAL

rqlite 10버전은 SQLite의 Write-Ahead Log(WAL)를 직접 제어하여 Raft 기반 분산 데이터베이스의 스냅샷 효율성을 크게 개선했다. 기존에는 전체 데이터베이스 복사로 비효율적이었으나, WAL을 활용해 변경분만 스냅샷하고, 체크포인트 시점을 rqlite가 직접 관리한다. 또한, WAL 체크포인트 실패 시 다양한 상태를 감지해 적절히 처리하며, 느린 리더로 인한 스냅샷 지연 문제도 최소화했다. 이로써 대용량 데이터베이스에서도 빠르고 일관된 스냅샷이 가능해졌다.

SQLite, left to itself, manages its own WAL: it checkpoints when the WAL grows, it checkpoints when the last connection closes,…
