Re: [grpc-io] Re: using grpc for push notification

[mscudieri78 via grpc.io]

Could you please repost the examples of th c++ async route guide demos, 
Would be very helpful.

Thanks, Marco.

Hi Chaitanya,

Could you please share async stream code? 
The link seem to be broken now.

thanks.

Re: [grpc-io] Re: using grpc for push notification

[chaitanya gangwar]

Oh i think i missed the grpc proto file. But its the same as present in git
repository example folder. This code is modification of example present in
grpc source. You just need to make a small change, add "stream" keyword in
return argument.

 I have added 2 variant of routeguide example, one for asyn stream with
 one rpc and other for async stream multiple rpc. You can take a look at the
 code. this was working with grpc 0_11 version. This will give you a good
 idea of how to use grpc for asyn stream.

 Assuming you had some "registry" of streams that represent clients
 to which you forward data:

 In your server implementation, you'd just register the
 StreamObserver (that's what its called in the Java runtime
 
 anyway).

 Here's example generated code for an endpoint with a streaming
 response: https://github.com/grpc/grpc-java/blob/master/exam
 ples/src/generated/main/grpc/io/grpc/examples/routeguide/
 RouteGuideGrpc.java#L80
 (That's the interface you implement on the server.)

 When your server receives data from whatever other source, it can
 consult this registry of streams and then call onNext to send the 
 client(s)
 data. Unregister when the stream errors or when you close the stream. 
 You
 close it via calling onComplete or onError (latter will send error 
 code to
 the client).

 providing the data to server.

 Can i do this with grpc without blocking the server and client.
 What i understand from grpc streaming is that client will be waiting

 the connection.

 please help, if i can do this using grpc and if yes how should i
 design this.

 thanks

Hi Chaitanya,

Thank you for you sharing! Can you provide the .proto file with it? It's 
hard to understand without the .proto file, and I can't change the code and 
recompile it. 

Thanks

Hi John,

I have added 2 variant of routeguide example, one for asyn stream with one
rpc and other for async stream multiple rpc. You can take a look at the
code. this was working with grpc 0_11 version. This will give you a good
idea of how to use grpc for asyn stream.

 Assuming you had some "registry" of streams that represent clients to
 which you forward data:

 In your server implementation, you'd just register the StreamObserver
 (that's what its called in the Java runtime
 
 anyway).

 Here's example generated code for an endpoint with a streaming
 response: https://github.com/grpc/grpc-java/blob/master/exam
 ples/src/generated/main/grpc/io/grpc/examples/routeguide/
 RouteGuideGrpc.java#L80
 (That's the interface you implement on the server.)

 When your server receives data from whatever other source, it can
 consult this registry of streams and then call onNext to send the client(s)
 data. Unregister when the stream errors or when you close the stream. You
 close it via calling onComplete or onError (latter will send error code to
 the client).

[John Coffey]

Chaitanya, 

that would be really useful, thanks, I will look forward to seeing the 
code.  It is strange that gRPC does not have asynchronous stream support, 
you would think this kind of listener/observe pattern would be a pretty 
popular feature.

Re: [grpc-io] Re: using grpc for push notification

[chaitanya gangwar]

Hi John,

When i was working on this, there was no example in grpc package to do the
same. Actually, what you need here is asynchronous streaming, but in
examples, there are 2 variant, one is synchronous stream (routeguide) and
normal async rpc (helloworld). You have to understand both the examples and
need to implement async stream yourself. I may have some poc code with me
where i tested this functionality. Ill check my repo and will post it to
you. May be that will be of some help for you.

Thanks

 Can i do this with grpc without blocking the server and client. What i
 understand from grpc streaming is that client will be waiting for data till
 server sends out the data and after receiving the data it closes the
 connection.

 please help, if i can do this using grpc and if yes how should i design
 this.
