writing schemas for data and a binary format for serializing data. +• They were created by Google to simplify and improve efficiency in programming, especially when dealing with APIs and multiple clients. +• A protocol buffer schema is similar to a Go struct but can be used across languages and formats (e.g. JSON) with a code generator. +• Using protocol buffers allows programmers to avoid error-prone tasks of rewriting data structures for each client language. +• Trade-offs include the need for a schema and potential compatibility issues, but especially in Go, these are considered minor compared to the benefits. +• Protocol buffers can be used as a schema language even when working with JSON. +• Comparison of Protocol Buffers to Swagger (OpenAPI) for data modeling +• Critique

+• The discussion centers around gRPC, its origins, and its marketing aspect. +• gRPC is derived from Google's internal system called Stubby, which uses protobuf-flavored HTTP/2. +• The protocol is relatively simple and could be described in a few paragraphs. +• The group acknowledges that there are multiple implementations of gRPC, but only one widely-used Go implementation (gRPC-Go). +• The discussion touches on the idea that having different trade-offs and implementation choices can be beneficial for developers. +• Buf is working on improving protocol buffers tools, including writing its own protobuf compiler from scratch and a schema registry. +• gRPC is intimately connected with Protobuf and using one requires considering the other +• gRPC has strengths in certain areas, but weaknesses in others, such as interoperability with net HTTP +• Connect is a drop-in replacement for gRPC that is wire-compatible and works with net HTTP +• Connect aims to make gRPC feel more like a part of the Go ecosystem, rather than a separate entity +• Perf-wise, using Connect or gRPC is generally comparable to using net HTTP +• The approach of using statically-typed languages like Go, TypeScript, and Python for APIs is deliberate +• Even dynamically-typed languages can benefit from type information at boundaries +• Using gRPC or Connect may be more suitable for internal communications rather than user-facing APIs +• Developer mindset plays a role in choosing between gRPC/Connect and traditional approaches +• The benefits of using gRPC with a JSON format for external
