SUMMARY:What’s So Bad About Cardinality Anyway? Rethinking Metrics in the
  Modern Observability Ecosystem
DESCRIPTION:For years\, observability teams have warned developers to avoid
  high-cardinality metrics. We treat cardinality like a natural disaster ra
 ther than something we can design for. But what if the fear comes not from
  inherent limits\, but from historical constraints baked into early metric
 s systems?This talk reexamines cardinality through a historical and archit
 ectural perspective. We’ll explore how the original Prometheus design cr
 eated cultural habits that persist\, and how modern systems change the equ
 ation. With remote-write storage\, Parquet-based engines\, OTLP-native pip
 elines\, exemplars\, and alternative backends like ClickHouse\, high-cardi
 nality data is no longer something we must avoid—it’s something we can
  use intentionally.Rather than asking how to stop cardinality\, we’ll as
 k what insights we’ve been missing by fearing it—and how to design obs
 ervability platforms that support flexible dimensionality without compromi
 sing reliability or cost.Key TakeawaysWhy cardinality fear is cultural and
  historical\, not fundamentalHow early metrics architectures shaped today
 ’s constraintsModern tools that enable safe high-cardinality analytics (
 Parquet\, ClickHouse\, exemplars)When to choose metrics vs traces vs logs 
 vs column storesPractical patterns for platform teams enabling—not restr
 icting—engineersTarget AudienceSREs\, platform/observability engineers\,
  DevOps\, backend developers\, architects\, and engineering leaders respon
 sible for telemetry strategy or cost control.\nSpeakers: Joel Verezhak\nTr
