Learning a few things about running SQLite

This article shares the author's experiences using SQLite as a database for a Django website. Key lessons include the importance of running ANALYZE to improve query performance (reducing a 5-second query to 0.05 seconds), and challenges with database cleanup operations that cause timeouts and worker crashes. The author suggests batching deletes and considers using PostgreSQL for concurrent writes. The content is focused on database management, query optimization, and practical IT/technology issues related to SQLite in production.
