Interested: do you also do heavy business logic with the data you receive ? How easy is it to refactor this logic ?

Or is your cluster more of an agnostic broker / message pump that lets other systems do the logic ?

it calculates running and time segment based average/high/low/tally values and drives alerts off of them. Processing is done in stages it's not particularly hard to change how one stage works as long as you aren't talking about major struct type changes or message format changes as those are a bit harder to rollout if not harder to implement.
