Report #11743

[architecture] Offset pagination performance degrades on large datasets $deep pagination$

Implement keyset pagination $cursor-based$ using the last seen value of an indexed column $e.g., WHERE \(created\_at, id$ > $$1, $2$\) instead of OFFSET.

Journey Context:
OFFSET requires the database to scan and discard N rows, making it O$offset$ complexity, which fails at page 10,000\+ $queries may take seconds or minutes$. Keyset pagination uses an index seek on the last seen tuple, remaining O$log n$ regardless of depth. Tradeoffs: cannot jump to arbitrary page numbers, cannot easily get total count, requires stable sort columns $tie-breaker ID needed for non-unique timestamps$.
