SQL Server: Windowing & Pagination: Overview

Module: Database-Specific Features

OFFSET/FETCH pagination (SQL Server standard) - Implement efficient pagination for web applications (used by Stack Overflow to paginate 50M+ questions)

Window functions (ROW_NUMBER, RANK, DENSE_RANK, NTILE) - Perform analytics without GROUP BY collapsing rows (LinkedIn uses for feed ranking)

Keyset pagination for large datasets - Avoid OFFSET performance issues on deep pages (Twitter uses for infinite scroll with 500M+ tweets)

PARTITION BY for grouped analytics - Calculate rankings within categories (Amazon uses for product rankings per category)

Window frames (ROWS vs RANGE) - Define calculation windows for running totals and moving averages (financial systems use for stock analysis)

Performance optimization - Index strategies and query patterns for fast pagination (Reddit optimizes for 1B+ posts with sub-50ms response times)
