There is a similar question regarding this. Let me quote what I had said there:

"GetMongo will continue to pull data from MongoDB based on the provided properties such as Query, Projection, Limit. It has no way of tracking the execution process, at least for now. What you can do, however, is changing the Run Schedule and/or Scheduling Strategy. You can find them by right clicking on the processor and clicking Configure. By default, Run Schedule will be 0 sec which means running continuously. Changing it to, say, 60 min will make the processor run every one hour. This will still read the same documents from MongoDB again every one hour but since you have mentioned that you just want to run it only once, I'm suggesting this approach."
