See [How can I use aggregations to query distinct values across all time grouped by first seen](https://discuss.elastic.co/t/how-can-i-use-aggregations-to-query-distinct-values-across-all-time-grouped-by-first-seen/25482/16) and the links to using an entity-centric indexing approach.

In your case the central "entity" would be a subscriber and you would be fusing data from multiple "event" indices.
