But is this a false dichotomy?

Update the package and your code gets faster.Fri, 14 Aug 2026 00:00:00 GMThttps://buf.build/blog/choosing-the-right-protobuf-integer-typehttps://buf.build/blog/choosing-the-right-protobuf-integer-typeProtobuf 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.Mon, 10 Aug 2026 00:00:00 GMT
