Claus Ibsen updated CAMEL-20277:
--------------------------------
Fix Version/s: 4.4.0
> camel-grpc: gRPC proxy with streaming
> -------------------------------------
>
> Key: CAMEL-20277
> URL: https://issues.apache.org/jira/browse/CAMEL-20277
> Project: Camel
> Issue Type: New Feature
> Components: camel-grpc
> Reporter: Ivan Mashtak
> Priority: Minor
> Fix For: 4.4.0
>
>
> For now it is possible to create gRPC proxy using the following configuration:
>
> {code:java}
> from("grpc://localhost:1101" +
> "/org.apache.camel.component.grpc.PingPong"
> )
> .toD("grpc://remotehost:1101" +
> "/org.apache.camel.component.grpc.PingPong" +
> "?method=${header.CamelGrpcMethodName}"
> ) {code}
> But that approach has major drawback: for server-streaming methods response
> stream will be collected to list. It means that client of that proxy will
> start to see stream of responses only after server completed the stream. It
> may be unacceptable especially for proxy - stream may consists of small
> messages but be huge by itself.
>
> I started from investigation of streamRepliesTo parameter, but there is no
> option to connect route defined by that parameter with consumer's
> StreamObserver.
