## AI overview

Hud describes its runtime code sensor, which gathers function-level production context and changes the depth of data collection when problems occur. The article explains that ClickHouse Cloud supports processing and correlating version-aware telemetry with high-cardinality data.

## Source excerpt

"High-cardinality data is core to how we track function-level behavior across versions. ClickHouse stood out because it handled that complexity natively, while other systems made it harder to work at that level of granularity."
