我想异步运行 OpenCPU 作业并从不同的会话中收集其结果。在Rserve+RSclient我可以执行以下操作：
RS.eval(connection, expression, wait = FALSE)
# do something while the job is running
然后当我准备好接收结果时调用：
RS.collect(connection)
如果作业仍在运行，则尝试收集结果并等待它们准备好，或者：
RS.collect(connection, timeout = 0)
如果我想检查作业状态并在它仍未完成时让它运行。
OpenCPU 是否可以在作业完成之前tmp/*/...接收带有结果 id 的路径？
It seems acording to this post that OpenCPU does not support asynchronous jobs. Every request between the browser and the OpenCPU server must be alive in order to execute a script or function and receive a response succesfully. If you find any workaround I would be pleased to know it. In my case, I need to run a long process (may takes a few hours) and I can't keep alive the client request until the process finishes.
