> We have a use case where a user has some old native code and they need it to
> work with storm, but sadly the code is not thread safe so they need to be
> sure that each instance of a specific bolt is in a worker without other
> instances of the same bolt. It also cannot co-exist with other bolts for a
> similar reason. I know that this is a fairly strange use case, but to help
> fix the issue we wrote a strategy for RAS that can do a simple search of the
> state space trying to honor these constrains and we thought it best to push
> it back then to keep it internal.
