WEBINAR
Observability on ClickHouse®: What Breaks at Scale and How to Model Around It
July 23 @ 9:00 am – 10:00 am PDT
Every ClickHouse: schema works fine at 10GB. Most fall apart somewhere between 1TB and 100TB, and it’s rarely for the reason you’d guess.
Last9 runs its entire observability platform (logs, metrics, and traces, all on one shared ClickHouse layer) at real production scale: 480M log lines a minute, 20M+ unique label combinations per metric, sub-second aggregations over unsampled data. Getting there meant hitting the failure modes everyone eventually hits: high-cardinality columns that break naive indexing strategies, retention and tiering schemes that either blow up storage costs or blow up query latency, and control-plane decisions about what to filter before data ever reaches ClickHouse.
In this session, Altinity and Last9 walk through the actual schema and architecture decisions behind a unified telemetry platform at scale: ORDER BY and cardinality tradeoffs, when to filter/reshape data before ingestion vs. after, tiered retention design (hot/warm/cold), and where “it’s fine in a demo” modeling choices turn into production incidents.
