Recording Rules: The Pattern for Fast Dashboards

Recording rules pre-compute. The pattern, the trade-offs, and the dashboards that get instant instead of slow.

The idea

Common queries are pre-computed and stored as new time series. Dashboards query the pre-computed series, not the raw.

Trade compute time at write for query time at read.

When it pays

Queries that take >1 second to render. Dashboards loaded multiple times per day.

Heavy aggregations across many series. The pre-computation amortises across reads.

Limits

Pre-computed series add cardinality. Watch the budget.

Recording rules need maintenance. Stale rules accumulate; quarterly audit.
