FS2 (“Functional Streams for Scala”) is a purely functional, effectful abstraction for stream processing on the JVM. Built on Cats Effect, it enables compositional resource-safe streaming workflows with robust error handling, back-pressure, pull/push semantics, and support for concurrent and interruptible pipelines.
Features
- Purely functional streams with Cats Effect integration
- Safe resource acquisition and disposal using compile-time guarantees
- Composable concurrent pipelines with back-pressure support
- Pull/homeostasis and push models unified in a single API
- Support for streaming connectors (e.g. HTTP via fs2-http, RabbitMQ, MQTT)
- Designed for efficient Scala code on both Scala 2 & Scala 3
