How to chain .preload() before .paginate() in AdonisJS to avoid N+1 queries, respect pagination metadata, and protect fillable guards.
Offset-based paging in Hibernate scans every skipped row, so deep pages get slow. Keyset pagination with WHERE id > :lastId reads only what you need — here's how to apply it safely.
