How blocks storage in Cortex reduces operational complexity for running Prometheus at massive scale
Cortex is a long-term distributed storage for Prometheus. It provides horizontal scalability, high availability, multi-tenancy and blazing fast query performances when querying high cardinality series or large time ranges. Today, there are massive Cortex clusters storing tens to hundreds of millions of active series with a 99.5 percentile query latency below 2.5s.
