| Anti-pattern | Why it’s bad |
|--------------|----------------|
| Indexing every column | Wasteful writes, huge storage, slow inserts. |
| Using LIKE '%term' | Leading wildcard disables B-tree index (use full-text or reverse index). |
| Index on NULL-heavy columns | B-trees ignore NULLs unless query uses IS NULL. |
| Over-relying on index hints | Forces optimizer to ignore better plans. |
| Ignoring index order in composite | INDEX (date, user_id) ≠ INDEX (user_id, date). | user_id) ≠ INDEX (user_id
