InfluxDB vs Prometheus

InfluxDB: Purpose-built time-series database, rebuilt in Rust on Arrow, DataFusion and Parquet for version 3. Prometheus: CNCF-graduated pull-based monitoring system with a local TSDB, PromQL and alerting rules.

key differences

  • InfluxDB is built for larger datasets (≤ 1 PB) than Prometheus (≤ 100 GB).
  • Horizontal scaling is native in InfluxDB and manual in Prometheus.
  • Only InfluxDB has joins, triggers, columnar storage, role-based access.
  • InfluxDB has a serverless option; Prometheus does not.
