What's the latest with gRPC? Carl and Richard chat with Irina Scurtu about her latest work with gRPC. Irina talks about the improved tooling with gRPC, including tools like Postman to help you see what's happening in a gRPC interaction, even decoding the binary data! The conversation also digs into the complexity of metadata with headers and trailers and the challenges of supporting multiple platforms and multiple type systems - but it works if you take the time to learn the details. And the results are fast and flexible communications!
