Итак:

```Python
q: str | None = Query(default=None)
```

...делает параметр необязательным со значением по умолчанию `None`, так же как:

```Python
q: str | None = None
```

```

The benchmark code defines default values for the parameters so if
you leave out any out JMH will run with each default value, one after
the other. This will run with `interval` set to `calendar year` then
`calendar hour` then `10d` then `5d` then `1h`:
```

			Optional:    true,
			Type:        "csv",
		},
		config.HelpKV{
			Key:         Vendor,

Таким чином:

```Python
q: str | None = Query(default=None)
```

...робить параметр необов’язковим зі значенням за замовчуванням `None`, що еквівалентно:

Navigate to “**Custom spark-defaults**” to configure MinIO parameters for `_s3a_` connector

![spark-config](https://github.com/minio/minio/blob/master/docs/bigdata/images/image9.png?raw=true "spark defaults")

Add the following optimal entries for _spark-defaults.conf_ to configure Spark with **MinIO**.
