Introducing FastPage: Faster offset pagination for Rails apps

Introduced the FastPage gem for ActiveRecord, which applies the MySQL deferred join optimization to `offset`/`limit` queries. This gem significantly improves the performance of deep pagination by reducing the database's workload. The post details how the deferred join technique works and provides benchmarks demonstrating its effectiveness compared to standard ActiveRecord pagination. It also offers guidance on when to use FastPage, suggesting its application for pages beyond a certain threshold to maximize performance benefits.
