- SQLite indexes require careful consideration for optimal performance.
- Composite indexes are more effective than multiple single-column indexes.
- The order of columns in an index affects query performance; more selective columns should come first.
- SQLite's query planner follows the rule: 'Left to right, no skipping, stops at the first range'.
- Partial indexes in SQLite require exact matching conditions between the index and query.
- Optimizing indexes and queries led to a ~35% speedup in Scour's ranking query.
- Understanding SQLite's query planner behavior is crucial for database performance tuning.
