Java client streaming api questions

[cr2...@gmail.com]

Hi

Are the Java steaming APIs thread safe ? 

If I have a StreamingObserver.onNext(<mydata>) with potentially multiple threads calling that

then  on the StreamObserver's implemented interface onNext method how can associate the response back to a specific 

 thread's call to the StreamingObserver.onNext(<mydata>) ?

Hope that made sense :)

Thanks in advance.

StreamObserver is not thread safe, so if multiple threads are producing data, you must synchronize the calls. You can find more details here:

http://www.grpc.io/grpc-java/javadoc/io/grpc/stub/StreamObserver.html

Can you elaborate on your use and why multiple threads are writing on this streaming call, rather than having a call per thread?

Hi Thanks for the reply-  I was under the initial assumption that separate streaming stubs would create separate connections .. but the connection is on the managed channel so at the moment I've moved to just creating one per thread call.
