The new index on the user_id column in the profiles table significantly improves query performance for user-specific profile retrieval operations, reducing full table scans during authentication and profile loading workflows.
The new index on the `user_id` column in the `profiles` table improves query performance when filtering or joining by user identifier, reducing full table scans during authentication and profile retrieval operations.
The profiles table previously lacked an index on the user_id column, causing full table scans during user profile retrieval. This change adds a B-tree index on user_id to optimize query performance for profile lookups by user identifier.
