Traditional TSDB label-set models degrade severely under this pattern.</p> <p>This article analyzes the time-series storage design of three mainstream RUM solutions: Sentry (open-source all-in-one), Datadog RUM (SaaS benchmark), and Grafana Faro (Grafana LGTM ecosystem extension). The common trend across all three is <strong>leveraging columnar OLAP instead of TSDB</strong>.</p>
