[architecture] Why does OFFSET pagination get slower and return duplicate rows?

Use keyset \(cursor\) pagination for stable, scalable feeds. Encode the last seen sort key in a cursor and query WHERE \(sort\_col, id\) > \(last\_sort, last\_id\); avoid OFFSET for user-facing infinite scroll.

Journey Context:
OFFSET forces the database to fetch and sort all rows up to the offset, then discard them; concurrent inserts cause duplicates or skipped rows. Keyset pagination is index-friendly and deterministic. The tradeoff is that you cannot jump to arbitrary page numbers, but that is usually fine for feeds. Use offset only for small result sets or cached counts; for high-volume lists the seek method is the standard fix.
