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