# getStatistics

## HTTP Request

```http
GET /api/v1/tables/:tableReference/variables/:variableName/statistics
GET /api/v1/tables/:tableReference/uploads/:uploadReference/variables/:variableName/statistics
GET /api/v1/queries/:queryId/variables/:variableName/statistics
```

{% hint style="success" %}
Variable statistics are typically computed the first time they are accessed, and afterwards are cached for future reference. If this endpoint is called on a variable without cached statistics, Redivis will attempt to compute statistics before returning the response.\
\
If, after 30 seconds, statistics have still not been computed, this endpoint will instead return a statistic object with empty attributes and `status == "running"`.
{% endhint %}
