Hi and thank you for all of your replies.
It has convinced me that giving reviving Edgent a try could be the best option.
I'll try to figure out how we can achieve that. For now I have to find a third
mentor and then we can get started.
I'll keep you posted.

Hi Julian,
Thanks for pointing to NiFi, I'll have a look at it. I used edgent at that
time since it was simple enough to get a custom topology up and running
without any added bloat.
Regarding the dataset, it is a series of unrelated events and definitely
partitioning is possible. But I was not worried about that aspect, since I
was focusing on placement of the topology and not on improving the
performance through parallelism of some sort. Is it why you asked that?
I'll start a new thread on the fault tolerance aspects. It should be
interesting to understand others' view on it.
