What can be a real-time tracking system for unique events?

Hello,
I am looking for a backend analytics system that will allow the display of the number of unique events on the chart.
The graph will display the sum of unique events for each hour.
Uniqueness criterion: userId + eventName
Data characteristics: for one campaign up to 200 million events, the number of campaigns is thousands. Campaign duration - from days to several years.
Granularity: Ideally adjustable, in practice granularity of 1 hour is sufficient.
