A gRPC channel should be reused when making gRPC calls. In either case, from a practical perspective this is stopping me from running the demo. From the path in your error message, I see that your client is running in an automated testing environment (Jenkins). The Kestrel server supports HTTP/3 by default. Streamed messages are sent as data on an existing HTTP/2 request and eliminates the overhead of creating a new HTTP/2 request for each unary call.

Is there a word in English to describe instances where a melody is sung by multiple singers/voices? Potentially something I have missed, but thought better get a bug created just in case. One of the first approach to implement retry was to fire off 2 tasks - one to receive packet on the stream from gRPC service, another - to control timeout. 1 Answer Sorted by: 0 HTTP/2 supports multiplexing, which allows multiple requests and responses to be sent and received over a single connection concurrently.

Seems basic configuration issue. a1exus July 28, 2019, 7:09pm 1 Hello World! TCP is great for communicating across a network, but inter-process communication (IPC) is more efficient when the client and service are on the same machine. To understand how to solve this, you need to know a minimal amount about how Docker's networking works. Client-side load balancing is a good choice when latency is important.
