Hardware Metadata gRPC Client

Overview

At Collins Aerospace, I developed a Hardware Metadata gRPC Client in Python that connects to any hardware device by IP and retrieves its full metadata in a secure, isolated way. Using multithreading and a dataclass-based wrapper, the tool ensures each client session stays completely segregated, with zero cross-client data leaks during live RF signal monitoring.

Key Features

• gRPC Connectivity: Dynamic client stubs auto-generated from .proto definitions
• Dataclass Wrappers: Typed request/response models for clear, maintainable code
• Multithreaded Fetching: Parallel metadata retrieval from multiple devices with low latency
• IP-Based Targeting: Connect to hardware endpoints directly by IP address
• Secure Isolation: Each thread runs in its own context to prevent data bleed

Built With

• Python 3.10+
• grpcio & grpcio-tools for gRPC communication
• dataclasses module for structured message handling
• concurrent.futures.ThreadPoolExecutor for multithreading
• In-house security libraries to enforce isolation policies

Impact

• Enabled real-time aggregation of device metadata across fleets of RF units
• Achieved zero cross-client data breaches in production tests
• Simplified client integration by swapping only IP and dataclass parameters
