Learning a few things about running SQLite
TL;DR
Running queries on SQLite can be slow if not properly optimized. By using the ANALYZE command, query performance improved dramatically from 5 seconds to 0.05 seconds.
✦ Why It Matters
Run the ANALYZE command on your SQLite database to optimize query performance immediately.
Key Takeaways
- Use the ANALYZE command to optimize SQLite query performance.
- Perform database cleanup in small batches to avoid timeouts.
- Consider incremental backups with Litestream for efficiency.
- Explore using a more robust database like Postgres for concurrent writes.
How It Works
The ANALYZE command in SQLite gathers statistics about the database, such as row counts and data distribution, which helps the query planner make better decisions. This can drastically improve query performance by allowing the database to choose more efficient execution plans.
