This documentation is for an unreleased version of Apache Flink Stateful Functions. We recommend you use the latest stable version.
Stateful Functions: A Platform-Independent Stateful Serverless Stack
A simple way to create efficient, scalable, and consistent applications on modern infrastructure - at small and large scale.
Stateful Functions is an API that simplifies the building of distributed stateful applications with a runtime built for serverless architectures. It brings together the benefits of stateful stream processing - the processing of large datasets with low latency and bounded resource constraints - along with a runtime for modeling stateful entities that supports location transparency, concurrency, scaling, and resiliency.
It is designed to work with modern architectures, like cloud-native deployments and popular event-driven FaaS platforms like AWS Lambda and KNative, and to provide out-of-the-box consistent state and messaging while preserving the serverless experience and elasticity of these platforms.
If you’re interested in playing around with Stateful Functions, check out our code playground. It provides a step by step introduction to the APIs and guides you through real applications.
