GraphQL Berlin Meetup #25 - Matteo Collina - GraphQL caching demystified ◭ How would you implement a performant GraphQL cache? How can we design a good algorithm for it? Is there a good Open Source solution that is efficient, scalable, and easy to deploy? How is the caching key computed? What about cache invalidations? Would it be possible to deduplicate resolver execution? This might be seen as daunting but in reality is all code and algorithms. In this talk we are going to walk through a GraphQL caching system that we have developed for Mercurius - one of the fastest GraphQL servers for Node.js. ◭ Matteo is Chief Software Architect at NearForm, where he consults for the top brands in the world. In 2014, he defended his Ph.D. thesis titled "Application Platforms for the Internet of Things". Matteo is a member of the Node.js Technical Steering Committee focusing on streams, diagnostics and http. He is also the author of the fast logger Pino and of the Fastify web framework. Matteo is an renowed international speaker after more than 60 conferences, including Node.js Interactive, NodeConf.eu, NodeSummit, JSConf.Asia, WebRebels, and JsDay just to name a few. He is also co-author of the book "Node.js Cookbook, Third Edition" edited by Packt. In the summer he loves sailing the Sirocco. ◭ Get in touch with Matteo: https://twitter.com/matteocollina ◭ Join our GraphQL Berlin Meetup group: https://www.meetup.com/graphql-berlin
