-## Use Cursor-Based Pagination Instead of OFFSET
-
-OFFSET-based pagination scans all skipped rows, getting slower on deeper pages. Cursor pagination is O(1).
-
-**Incorrect (OFFSET pagination):**
-
-```sql
--- Page 1: scans 20 rows
-select * from products order by id limit 20 offset 0;
-
--- Page 100: scans 2000 rows to skip 1980
-select * from products order by id limit 20 offset 1980;
-
--- Page 10000: scans 200,000 rows!
-select * from products order by id limit 20 offset 199980;
-```
-
-**Correct (cursor/keyset pagination):**
-
-```sql
--- Page 1: get first 20
-select * from products order by id limit 20;
--- Application stores last_id = 20
-
--- Page 2: start after last ID
-select * from products where id > 20 order by id limit 20;
--- Uses index, always fast regardless of page depth
-
--- Page 10000: same speed as page 1
-select * from products where id > 199980 order by id limit 20;
-```
-
-For multi-column sorting:
-
-```sql
--- Cursor must include all sort columns
-select * from products
-where (created_at, id) > ('2024-01-15 10:00:00', 12345)
-order by created_at, id
-limit 20;
-```
