The original title is "Implementing Exponential Backoff Retry Logic for SQLite Concurrent Write Contention"

Short summary

A practical guide to solving SQLite 'database is locked' errors under concurrent write load from multiple AI agents using exponential backoff with jitter. The author provides a complete production-ready setup combining a retry wrapper, connection pooling, and WAL mode to reduce lock contention. Key parameters include a 30-second busy timeout, 5 max retries with 100ms base delay, and random jitter to prevent thundering-herd retries.

• •Exponential backoff with jitter prevents simultaneous retries when multiple agents hit SQLite lock contention
• •Connection pooling (size 5) and WAL mode reduce lock contention by limiting concurrent connections and enabling concurrent reads during writes
• •Complete production code includes retry config, connection pool, deadlock detection, and database initialization with proper PRAGMA settings
