On: Understanding gRPC, OpenAPI and REST and when to use them in API design (2020)

How could gRPC be simpler without sacrificing performance?

[jeeyoungk → pphysch]

There's two parts to gRPC's performance

- 1. multiplexing protocol implemented on top of HTTP/2 - 2. serialization format via protobuf

For most companies, neither 1 or 2 is needed, but the side effect of 2 (of having structured schema) is good enough. This was the idea behind twrip - https://github.com/twitchtv/twirp - not sure whether this is still actively used / maintained, but it's protobuf as json over HTTP.

What kind of performance? Read? Write? Bandwidth?

grpc "urls" and data are binary.

binary with schema separation.

3x smaller payload.
