Couple of points: > I have figured out a way to add interceptor in server builder to add compression with type gzip You don't need an interceptor to add custom codec compression on the server side. Just use ServerBuilder.compressorRegistry(CompressorRegistry)

[grpc-io] Re: textual description in HealthCheckResponse

Normally the health checks are used by automated probers/health-checkers so the description is not needed there. I can see use-cases where the description is useful. The doc https://github.com/grpc/grpc/blob/master/doc/health-checking.md provides the context for the current proto and the actual

I have already replied on your StackOverflow thread as follows: Nothing in the gRPC stack seems to cause this limit. What's the average response time on the server side? It looks like you are limited by the ephemeral ports or TCP connection limit and you may want to tweak your kernel as describ

Sorry, just realized you are using client streaming. If you need to share the resource just between 2 methods of the same service. Can you get rid of your lock and just use directExecutor https://github.com/grpc/grpc-java/blob/master/api/src/main/java/io/grpc/ServerBuilder.java#L58 ? Alterna

[grpc-io] Re: Building a grpc reverse proxy using client headers

Envoy proxy uses xDS to dynamically change the routing configuration - some of these can be header matching rules that encapsulate your dynamic logic. This of course requires an "xDS" server to supply the route (and other dependent) configuration. In gRPC too there is support for xDS on the cl

Copy constructor implies copying object to the same type. You can use toBuilder() on the first object to get a builder that enables you to build the second object with the same

[grpc-io] A29: xDS-Based Security for gRPC Clients and Servers

Hello, I have created a PR https://github.com/grpc/proposal/pull/184 for "xDS-Based Security for gRPC Clients and Servers" which describes adding transport security (TLS or mTLS) to xDS-orchestrated gRPC connections. Note that xDS support to gRPC (client side) was already described in A27: xDS

Re: [grpc-io] Re: In a unary service, shouldn't onError after onNext be an illegal call?

StreamObserver is used for both streaming as well as unary responses. For streaming you call onNext in a loop followed by either onCompleted or onError. Unary is a special case of this where onNext is called at most once followed by onCompleted or onError. The grammar at https://github.com/grpc

[grpc-io] Re: Is it always recommended to use matching versions of gRPC for all languages in the same system?

You should be able to move to the recent version of gRPC Java in your use-case. Unless you know of a specific feature in the new version affecting the wire protocol (very unlikely) I don't see why moving to the newer gRPC Java version would be problematic for you. On Thursday, March 5, 2020 at

Your approach looks fine and seems to address the issue for multiple threads. I was trying to see if you could do without creating UUID and just use the ClientCall object reference as the key in the map but PickSubchannelArgs passed to RoundRobinLoadBalancer.ReadyPicker.pickSubchannel only give
