## InfluxDB: High-throughput time-series database

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

## Trade-offs

| Pros                                       | Cons                                |
|--------------------------------------------|-------------------------------------|
| Very high write throughput                 | Different ecosystem than Prometheus |
| Three query languages: SQL, InfluxQL, Flux | Storage grows quickly               |
| Built-in downsampling                      | Learning curve for either language  |
| Strong retention policies                  | Cloud version can be expensive      |

## Query language support by version

| InfluxDB Version       | Query Languages     |
|------------------------|---------------------|
| 3.x / Cloud Serverless | SQL, InfluxQL, Flux |
| 2.x                    | InfluxQL, Flux      |
| 1.x                    | InfluxQL, Flux      |

## Best for

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