About fluvio
Fluvio is a distributed data streaming engine written in Rust, distributed under the Apache 2.0 license and developed in the fluvio community repository. It is described as composable, declarative and stateful: a streaming runtime that pairs with Stateful DataFlow, a distributed stream processing framework, so that a single system covers both the transport of event streams and the transformation of that data while it is in motion. The project sits in the Rust and cloud native ecosystem and is published on crates.io, with documentation hosted at fluvio.io.
