gRPC message exceeds maximum size 4194304: 5145024 java

Question

On grpc client I am getting this error after calling the rpc method in server. I am using grpc-spring-boot-starter (java). Please tell me how to increase response size.

Answer 1

• If you are using official grpc library then create client in following way.

ManagedChannel channel = ManagedChannelBuilder.forAddress("localhost", 9089).usePlaintext().maxInboundMessageSize(Integer.MAX_VALUE).build();

productsBlockingStub prodStub = productsGrpc.newBlockingStub(channel);

You can refer the grpc project here. Just add modification formaxInboundMessageSize

• If you are using grpc-client-spring-boot-starter then you can either.

@GrpcClient("greeting-service")
    private GreetingServiceGrpc.GreetingServiceBlockingStub greetingServiceBlockingStub;

    greetingServiceBlockingStub = greetingServiceBlockingStub.withMaxInboundMessageSize(Integer.MAX_VALUE);
    greetingServiceBlockingStub = greetingServiceBlockingStub.withMaxOutboundMessageSize(Integer.MAX_VALUE);

Or add this in props.

grpc.client.greeting-service.max-inbound-message-size=9155241000
grpc.client.greeting-service.package-max-inbound-message-size=9155241000
grpc.client.greeting-service.server.max-inbound-message-size=9155241000
