# InfluxDB: High-throughput time-series database

**What it’s for:** High-volume metrics including IoT sensors, industrial monitoring, and sub-second precision data.

## Good to know

- Built for high write throughput, which suits high-volume, high-frequency data
- Built-in downsampling and retention policies help manage storage as data ages.
- The query language depends on your version.

## Query language support by version

| InfluxDB version                 | Query languages         |
|----------------------------------|-------------------------|
| 1.x                              | InfluxQL (Flux in 1.8+) |
| 2.x                              | Flux, InfluxQL          |
| 3.x (including Cloud Serverless) | SQL, InfluxQL           |

## Best for

- IoT and sensor data
- Industrial monitoring
- High-frequency metrics (sub-second)
