Apache Arrow Flight is a gRPC based protocol for exchanging Arrow data between processes. See the blog post [Introducing Apache Arrow Flight: A Framework for Fast Data Transport](https://arrow.apache.org/blog/2019/10/13/introducing-arrow-flight/) for more information.
This crate provides a Rust implementation of the [Flight.proto](../../format/Flight.proto) gRPC protocol and provides an example that demonstrates how to build a Flight server implemented with Tonic.
