Replacements
Listings that take over the same core job as M3DB.
VictoriaMetrics
Store and query monitoring metrics in a time-series database.
VictoriaMetrics supports Prometheus-compatible workflows with both single-node and clustered deployments, making smaller setups possible, with enterprise capabilities licensed separately.
Grafana Mimir
Store Prometheus-compatible metrics over long periods at distributed scale.
Grafana Mimir stores Prometheus-compatible metrics long term with multi-tenancy and Grafana integration under AGPL-3.0, though distributed operation needs substantial configuration.
InfluxDB
Store time-stamped measurements for monitoring and real-time applications.
InfluxDB is a time-series database with self-hosted and managed editions, though features and compatibility differ significantly between its product generations.
GreptimeDB
Store observability data in a database queried through SQL and PromQL.
GreptimeDB stores time-series telemetry queried through SQL and PromQL, with object-storage-oriented deployments under Apache-2.0 and a freemium model.
TimescaleDB
PostgreSQL extension that turns Postgres into a scalable time-series database.
TimescaleDB extends PostgreSQL for time-series workloads, keeping Postgres tooling, while advanced clustering and cloud features sit behind the paid offering.
QuestDB
Query time-series data with a database focused on SQL and high-rate ingestion.
QuestDB focuses on time-oriented SQL and high-rate ingestion rather than Prometheus compatibility, with managed and enterprise capabilities under separate terms.
