Parsing Protobuf Like Never Before · mcyoung

A deep dive into hyperpb, a high-performance Go protobuf parser that uses table-driven parsing instead of code generation. The library implements a virtual machine interpreter with extensive optimizations including arena memory management, zero-copy string handling, profile-guided optimization (PGO), and register-based parser state management. It outperforms existing Go protobuf parsers while maintaining full conformance to the protobuf specification, unlike some competitors that sacrifice correctness for speed.
