The article discusses the integration of Dragonfly, a next-generation in-memory data store, with Relay, a server-side caching solution for PHP applications. It highlights that Dragonfly has outperformed existing in-memory data stores such as Redis and Memcached, making it an ideal candidate for next-generation caching solutions. The integration of client tracking API support in Dragonfly allows it to serve as a backend caching data store for Relay. Evaluation results show that Dragonfly's performance continues to scale even after 512 workers, significantly outperforming the single Redis instance. This makes Dragonfly an ideal data store for Relay to achieve highly efficient next-gen caching infrastructure.
