What are InfluxDB and Grafana Mimir?
InfluxDB
InfluxDB is an open-source time series database designed for high write and query loads of metrics, events, and analytics data. It powers monitoring dashboards, IoT data collection, and real-time analytics.
- High-throughput time series storage
- SQL and Flux query support
- Built-in retention policies
- Telegraf collector ecosystem
Grafana Mimir
Grafana Mimir is an open-source, horizontally scalable, highly available, multi-tenant time series database for Prometheus and OpenTelemetry metrics. It is designed to store and query hundreds of millions of active series.
- Massive cardinality support
- Multi-tenant by design
- Fast query engine
- Object storage backend
