And then a C programmer comes in and slams sendfile. That’s the main advantage of HTTP/1.1. Of course TLS throws a wrench in it, but once kTLS is actually good

And then a C programmer comes in and slams sendfile. That’s the main advantage of HTTP/1.1. Of course TLS throws a wrench in it, but once kTLS is actually good (ahem), it’ll work. In all seriousness, don’t do large file transfers over gRPC, except in a pinch for small files. As soon as e.g API gateways are introduced in the mix, stuff can go south very quickly: increased allocation, GC pressure, network usage, etc. Just use presigned S3 URLs.
