protobuf performance go parsing validation

hyperpb dynamic parser matches generated code speed

Runtime-compiled Protobuf parser in Go achieves 10x faster parsing than dynamicpb and 3x faster than hand-written generated code, enabling schema-driven broker-side validation at scale.

Summary

Eliminates parsing throughput as a bottleneck for generic Protobuf services. Shifts broker-side validation from compute-prohibitive to practical, directly reducing invalid data slipping into message streams and downstream failures.

Why it matters

Implementation verdict

Replaces dynamicpb for throughput-critical paths. Requires caching compiled message types (slow optimization pass) and reflection-only field access. Production-ready now; evaluate if your validation pipeline hits dynamicpb bottlenecks.

Sources

1.10x faster than dynamicpb, the standard Go solution for dynamic Protobuf
2.3x faster than parsing with generated code
3.hyperpb requires you to compile a parser at runtime, much like a regular expression library. The compilation step is pretty slow, because it's an optimizing compiler
4.hyperpb currently only supports access by reflection
