Overview
This Pull Request enhances middleware support for Apache Arrow Flight using C#, focusing on improved metadata header management and propagation for better observability and extensibility. It also provides handling for HTTP/HTTPS communication.
Key Features
- Complete Header Propagation: Ensures accurate propagation of gRPC metadata headers throughout middleware lifecycle events.
- HTTP/HTTPS Handling: Supports middleware integration and metadata propagation for HTTP and HTTPS communications.
- Middleware Lifecycle Management: Supports reliable middleware hooks (OnBeforeSendingHeaders, OnHeadersReceived, OnCallCompleted).
- Enhanced Testing: Adds comprehensive integration tests to verify correct middleware behavior.
Impact
- Improves middleware reliability and simplifies debugging.
- Enhances transparency in gRPC and HTTP/S communication within Flight-based applications.
