Storm doesn't naturally support dynamic topologies and is rather resource hungry, which needs a bit advanced planning. I was looking @ Storm for my own pipelining product (bip.io) very early on and shied away as too high an opportunity cost for self-hosting users/devs to be bothered with. On a Rasberry Pi for example, forget about it. Without being able to create dynamic graphs it otherwise just ends up being a simple message bus (anti-pattern).
