fastflight 0.2.1

FastAPI and Arrow Flight integrated server offering efficient dual-protocol support for both REST and gRPC data streaming.

FastFlight

FastAPI + Arrow Flight Server

Introduction

This project integrates a FastAPI server with an embedded Arrow Flight server, offering a dual-protocol solution for handling both HTTP REST and gRPC requests efficiently.

• FastAPI Server: Provides a robust and high-performance HTTP REST service.
• Arrow Flight Server: Embedded within the FastAPI application, it directly handles gRPC requests, enabling fast and scalable data retrieval.
• REST to Flight Integration: A specialized REST endpoint forwards data requests to the Arrow Flight server, streaming the data back to the client seamlessly.

How does it work?

With FastAPI

1. Run the flight server and the FastAPI server in separate processes
2. Test by posting query params to the /fastflight/ endpoint

Without FastAPI

1. RUn the flight server
2. Test by posting flight ticket to the flight server endpoint.
3. Or, use the flight_client to help with the data retrieval.

How to add a new data source type?

1. Add a new data source type to the enum in models/data_source
2. Add a new params class in models/params. Make sure the new params class is registered with the new data source type
3. Add a new data service to handle the new params
