Arrow Flight is more than “just a file format.” In this quick walkthrough, I break down what Flight is, why gRPC makes it perfect for streaming Arrow record batches, and how the core RPC methods work (ListFlights + DoGet).
Then we build a tiny Python Flight server that:
Lists Parquet files in a public S3 bucket
Uses Flight methods to return schemas and stream data back to a local client
If you want a fast mental model for Flight, plus a practical “hello world” you can adapt for real services, this is it.
