Optimization Tips
Add single_column index: add_index :posts, :published - Fast lookups for published = value queries
Add single_column index: add_index :posts, :user_id - Fast JOIN execution
Add covering index: add_index :posts, ["published", "posts.title", "posts.content", "users.name"], name: 'covering_idx_posts_published' - Index-only scan without table access
Index Optimization - Review indexes on the 'posts' table. Consider composite indexes for WHERE clauses.
