DjangoCon Europe 2024: Learn how to use SQLite in production, overcome its limitations, and optimize performance and reliability in your Django applications.

Key takeaways

SQLite is a single-file database that can be used in production, but has limitations, such as blocking writes and poor performance under heavy loads.
Django’s default settings for SQLite need to be adjusted for production use to improve performance and reliability.
To overcome the limitations of SQLite, consider splitting writes into separate database files, or using a separate database server.
Write-ahead logging can improve write performance, but may not be compatible with all applications.
SQLite does not support transactions, which can cause problems when reading and writing to the database simultaneously.
To handle transactions, consider using a separate database server or implementing a custom solution.
Acquiring a lock on the database can be slow and may cause performance issues; consider using a light FS to improve performance.
Online backups can help prevent data loss in case of crashes or corruption.
SQLite supports full-text search, which can be useful for certain applications.
The transaction_mode option in Django 5.1 can help improve performance and reliability of SQLite in production.
Care should be taken when using SQLite in production, as it can be prone to database corruption and data loss.
Consider splitting large tables into smaller files to improve performance.
SQLite can be used as a read-only database, which can help improve performance and reliability.
Online forums and communities can be a valuable resource for troubleshooting issues with SQLite and Django.
It is important to understand how SQLite works and how to configure it correctly for production use.
