Modern Protobuf and gRPC

we just migrated our gRPC services to the ConnectRPC protocol instead. this turned out to be a fairly simple migration, but unlocks a whole bunch of new features for Hatchet in the next few months. gRPC is fantastic, but support across runtimes isn't great. in particular, we've had a bunch of requests for serverless runtimes like @Cloudflare Workers which we haven't been able to support because of gRPC compatibility issues. the original serverless runtimes were built around the fetch() API, which is missing a bunch of http/2 features that we need. we've been quietly waiting on gRPC support across these runtimes -- and Cloudflare just rolled it out in beta! -- but demand was high enough that we're just sending it. The great part about ConnectRPC is that it's fully gRPC compatible, so existing clients will still work. Just a 10/10 dev experience overall: connectrpc.com/ full serverless and sandbox support coming soon.

How well do you actually know Protocol Buffers? We put together a quick interactive quiz covering schema design, field rules, and wire format mechanics. protobuf.com/quiz/ The questions are now randomly selected from a question bank so retrying will give you a few new questions. #protobuf #grpc #quiz

Quiz | Protobuf Explained

A Protocol Buffers quiz that draws random questions from a large bank: a normal level on schema fundamentals and a hard level on the wire format and runtime behavior.

Protovalidate performance has improved dramatically. 3x faster in Go, 10x faster in Java, 13x faster in TypeScript and 484x faster in Python. No, that wasn't a typo. It really is that much faster than before. buf.build/blog/faster-protov…

A faster Protovalidate · Buf

Go, Java, and TypeScript now run Protovalidate's standard rules as native code, while protovalidate-py 2.0 replaces its pure-Python core with a much faster native extension.

This is an older post, but Connect-Query is a library that deserves more attention. It makes it trivial to pull in data from ConnectRPC servers using Tanstack Query. It simplifies state management and makes querying for data extremely simple. buf.build/blog/introducing-c…

Working through review on this taught me more about the internals of a real, widely-used RPC library than reading its docs ever could — signed commits, CI conventions, and genuinely thoughtful review comments about where test assertions should actually live. If you're already comfortable with gRPC and curious about an alternative that removes a lot of its operational friction, ConnectRPC is worth exploring properly. connectrpc.com | github.com/connectrpc/connec… #TechTwitter #OpenSource #Go #buildinpublic

Storing the three header maps as fields on the struct, created once via a new constructor (newErrStreamingClientConn), instead of allocating fresh maps on every accessor call. The accessors now return the stored fields, matching how every other connection implementation in the codebase already behaves. Added a dedicated test, TestErrStreamingClientConnHeadersAreStable, that fails against the old behavior and passes with the fix. Full diff: github.com/connectrpc/connec…

There are 10 different integer types in Protobuf. That honestly feels like about nine too many. Let's break down what actually separates them under the hood and how to pick the right one without overthinking your schema. buf.build/blog/choosing-the-…

Protobuf Tip #10: Choosing the right integer type · Buf

Protobuf has ten integer types. Use int64. In Go, even the slow cases decode a thousand integers in a few microseconds, so the choice almost never matters.
