Problem

We run a cloud platform for design and engineering software, and every desktop and browser session emits telemetry (documents opened, features used, render jobs, license checks) at roughly 2 billion events a day. Two groups consume that one stream on very different clocks: the licensing team enforces concurrent-seat limits and shows collaboration presence within seconds, while finance bills customers monthly on metered feature usage and the product org builds adoption reports on a daily cadence. The metered-usage figures land on invoices, so each billable event has to be counted once and only once.
