Index Introduction
Understand what SQLite indexes are, how they speed lookups, and the tradeoff they introduce for writes.
When to Use Indexes
Decide when SQLite indexes are worth adding by balancing read speed benefits against write and storage costs.
Create Index
Create regular SQLite indexes on columns used in filters and joins to improve read performance.
Unique Index
Enforce uniqueness and improve lookup performance in SQLite using UNIQUE indexes.
Composite Index
Build multi-column indexes in SQLite and apply leftmost-prefix rules to match query patterns correctly.
Dropping Indexes
Remove unneeded SQLite indexes safely with DROP INDEX and verify cleanup with metadata commands.
