Since Go's API is synchronous/blocking, I am pretty sure that sender always block until message is actually sent, which will respect HTTP/2 flow control windows.
If you want an async API, where a sender can queue up messages even before the receiver can accept them, you could push them into a buffered channel and have another goroutine that is de-queueing from the channel and writing to the receiver as allowed by flow control. Java is different because its API is completely async and non-blocking. So backpressure requires more sophistication in the app code. ---- *Josh Humphries* jh...@bluegosling.com On Wed, Oct 25, 2017 at 8:21 AM, <elda...@gmail.com> wrote: > > Hi, > > Is it possible to perform manual flow control in the RPC call level in > grpc-go? > > I'm looking for something like the flow control mechanism of the grpc > library for java: > https://github.com/grpc/grpc-java/tree/master/examples/src/ > main/java/io/grpc/examples/manualflowcontrol > > I would like my clients/servers to have the option to specify for the > other side whatever they are ready to receive new messages or not. > > I looked for this functionality in grpc-go documentation and the source > code but only found option to tune the window size of the http2 transport > layer. > Is this functionality implemented in grpc-go? > > Best, > Eldad. > > -- > You received this message because you are subscribed to the Google Groups " > grpc.io" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to grpc-io+unsubscr...@googlegroups.com. > To post to this group, send email to grpc-io@googlegroups.com. > Visit this group at https://groups.google.com/group/grpc-io. > To view this discussion on the web visit https://groups.google.com/d/ > msgid/grpc-io/c2b0653a-3ba5-4fd6-9164-dd1432c2af16%40googlegroups.com > <https://groups.google.com/d/msgid/grpc-io/c2b0653a-3ba5-4fd6-9164-dd1432c2af16%40googlegroups.com?utm_medium=email&utm_source=footer> > . > For more options, visit https://groups.google.com/d/optout. > -- You received this message because you are subscribed to the Google Groups "grpc.io" group.
