InfluxDB is a time series database built from the ground up to handle high write and query loads. InfluxDB is meant to be used as a backing store for any use case involving large amounts of timestamped data, including DevOps monitoring, application metrics, IoT sensor data, and real-time analytics.
Here are some of the features that InfluxDB currently supports that make it a great choice for working with time series data.
- Written entirely in Go. It compiles into a single binary with no external dependencies.
- Clustering is built in. Nothing else is needed to make data highly available (unlike Redis, ZooKeeper, Cassandra, and others).
- Simple, high performing write and query HTTP(S) APIs.
- Plugins support for other data ingestion protocols such as Graphite, collectd, and OpenTSDB.
- Expressive SQL-like query language tailored to easily query aggregated data.
- Tags allow series to be indexed for fast and efficient queries.
- Retention policies efficiently auto-expire stale data.
- Continuous queries automatically compute aggregate data to make frequent queries more efficient.
- Built in web admin interface.
The current version of InfluxDB is 0.9.6.1. Clustering, replication, and high-availability should be considered in an alpha state.
