# Estimated Scan Duration

### Condition

Scan for this query will not be completed for a long time. Usually there is no point in waiting. This warning indicates queries trying to process enormous amount of data relative to warehouse size.

### How to fix

* Check query text for mistakes and typos.
* Process data in smaller chunks.
* Increase warehouse size.

### Example

```
    EstimatedScanDurationCondition(
        min_estimated_scan_duration=60 * 60 * 2,  # query scan is estimated to take longer than 2 hours
        warning_duration=60 * 10,  # warning after 10 minutes
        kill_duration=60 * 20,  # kill after 20 minutes
    ),
```

### Specific arguments

* **min\_estimated\_scan\_duration** (int) - how long scan is expected to take based on current estimation, in seconds (recommended min value is at least 1 hour)
