Plot twist: It's not actually scalable because no amount of tools and buzzwords can compensate for the lack of experience in proper architecture for scaling.
> For the uninitiated, Linear is a project management tool that feels impossibly fast. Click an issue, it opens instantly. Update a status and watch in a second browser, it updates almost as fast as the source. No loading states, no page refreshes - just instant, interactions.
How garbage the web has become for a low-latency click action being qualified as "impossibly fast". This is ridiculous.
> The moment of capturing a measurement is known as a metric event
Which suspiciously reads like a log.
In practice, a metric is an aggregate of events (the "metric events") when you're not interested in the individual event but, but in the aggregate itself. For practical reasons this is not implemented with logs but with more primitive technical events emission.
This is not fundamentally incompatible notions. If you do an electrocardiogram, you might be interested in your BPM, but it is deduced by the full log of each beat. The segregation we do in computing is more practical than fundamental.
