             Summary: Cache Stream response should send asynchronously
                 Key: ISPN-8339
                 URL: https://issues.jboss.org/browse/ISPN-8339
             Project: Infinispan
          Issue Type: Bug
          Components: Distributed Execution and Map/Reduce
            Reporter: William Burns
             Fix For: 9.2.0.Alpha1


When a cache stream completes a request it sends that back to the requestor. Currently this is using RpcManager.invokeRemotely such as [1]. This is causing the remote nodes to use a remote thread to wait for the response to process. We should instead send this asynchronously so we don't have to keep the remote thread used. This can cause exhaustion if you have too many requests since these responses are also processed on the remote thread pool.
