protobuf-py: Protobuf for Python, without compromises
Summary
protobuf-py is a Python-native Protobuf runtime from Buf that keeps message data in Python, uses a Rust accelerator for parsing/serializing, and offers full protocol buffer spec support without wrapping Google's runtime. The article argues this approach provides a more Pythonic API and shows benchmarks where end-to-end performance can beat the C-based upb in real workloads. It also discusses code generation outputs and how to integrate protobuf-py into existing Python projects.
