if [single-tenant infrastructure][ref-dedicated-infra] is used. Check out the
[VPC connectivity guide][ref-cloud-conf-vpc] for details.

### Query tagging

Set a [query tag][snowflake-docs-query-tag] on the connection so that queries
Cube sends to Snowflake are labeled in `QUERY_HISTORY`. There's no environment
variable for this; set `queryTag` from a custom [`driverFactory`][ref-driver-factory]
instead of returning a plain options object:

```javascript
const SnowflakeDriver = require('@cubejs-backend/snowflake-driver');

module.exports = {
driverFactory: () =>
new SnowflakeDriver({
queryTag: 'cube',
}),
};
```

The tag is set once per connection, not per query — all queries issued over
that connection carry the same tag.
