Does this require a separate data source (e.g. a message queue) to ingest and log the events before reacting to them? Or could you retroactively use the mongodb oplog? I imagine there is way too much data for the oplog to be feasible in this case. And if you didn't design the system from day 1 around an event model, wouldn't it be difficult to retroactively introduce this new architecture?
