# Environment Variables

<Warning>
  We are sunsetting our SDKs and will no longer add new features, security patches, bug fixes, or technical support for them. To access the latest capabilities and ongoing improvements, we encourage you to migrate to our [RESTful API](/api-rest/introduction).

  SDK support will officially end on **December 31, 2026**. On this date, the underlying endpoints used by the SDKs and related documentation will be decommissioned.

  To avoid any disruption to your services, please ensure your migration is complete by that date.

  For migration assistance, please contact us at [support@bigdata.com](mailto:support@bigdata.com).
</Warning>

The following environment variables if available will be taken:

* `BIGDATA_USERNAME`
* `BIGDATA_PASSWORD`
* `BIGDATA_API_KEY`
* `BIGDATA_MAX_PARALLEL_REQUESTS`. Default 10

<Note>
  Increasing the default value of `BIGDATA_MAX_PARALLEL_REQUESTS`
  increases the memory and socket consumption. More information
  [here](https://urllib3.readthedocs.io/en/latest/advanced-usage.html#customizing-pool-behavior)
</Note>

Example:

```python theme={null}
# Bigdata username and password
BIGDATA_USERNAME=<your_email_address>
BIGDATA_PASSWORD=<your_password>

# Bigdata API key
BIGDATA_API_KEY=<your_api_key>
```

<Warning>
  `BIGDATA_USER` -> Deprecated, use `BIGDATA_USERNAME` instead.
