HOW NETFLIX REALLY USES JAVA

Summary from the TLDR Web Dev newsletter

Netflix's Java architecture has evolved significantly from its Groovy-based backend-for-frontend model. The company transitioned to a GraphQL Federation architecture, eliminating the need for reactive programming paradigms like RxJava. This shift simplified development, as GraphQL's explicit field selection reduces the complexity of creating device-specific APIs. Netflix heavily utilizes Java, currently on version 17 with active testing of version 21, and is looking forward to using virtual threads to scale easier.
