The number of spout and bolt executors can be changed at run time, but not the number of tasks. The number of worker processes can also be changed. You cannot change the layout of the topology by adding or removing spouts or bolts. If you need to add data sources without down time one thing you can do is have a spout that reads off a queue and then add components that push to the queue.
