# Connect Soda to Trino

> For Soda to run quality scans on your data, you must configure it to connect to your data source.\
> To learn how to set up Soda and configure it to connect to your data sources, see [Get started](https://docs.soda.io/soda-documentation/soda-v3/quick-start-sip/setup-guide).

## Connection configuration reference

Install package: `soda-trino`

Reference [Trino documentation](https://trino.io/docs/current/overview/concepts.html) for assistance.

```yaml
data_source my_datasource_name:
  type: trino
  host: my.trino.host
  catalog: datalake
  schema: cw_dq
  auth_type: OAuth2ClientCredentialsAuthentication
  oauth:
    token_url: https://token-url.test.com/token
    client_id: XXX
    client_secret: YYY
    scope: "scope1 scope2" # optional
    grant_type: client_credentials # optional, this is default value
```

#### Core connection properties

<table><thead><tr><th width="176.76666259765625">Property</th><th width="111.75">Required</th><th>Description</th></tr></thead><tbody><tr><td><code>type</code></td><td>yes</td><td>Identify the type of data source for Soda. Must be <code>trino</code> in this case.</td></tr><tr><td><code>host</code></td><td>yes</td><td>Provide a host identifier.</td></tr><tr><td><code>catalog</code></td><td>yes</td><td>Provide an identifier for the catalog which contains schemas and which references a data source using a connector. See <a href="https://trino.io/docs/current/overview/concepts.html#catalog">Catalog</a> in the Trino documentation.</td></tr><tr><td><code>schema</code></td><td>yes</td><td>Provide an identifier for the schema in which your dataset exists.</td></tr><tr><td><code>auth_type</code></td><td>yes</td><td><p>Authentication mode. Add <code>OAuth2ClientCredentialsAuthentication</code> to use OAuth 2.0 client credentials flow.</p><ul><li><code>BasicAuthentication</code> in combination of user + password, or</li><li><code>JWTAuthentication</code> in combination with <code>access_token</code> and optionally username.</li><li>Default: <code>BasicAuthentication</code>.</li></ul></td></tr><tr><td><code>source</code></td><td>no</td><td>Trino-internal label for the connection. Default: <code>soda-core</code></td></tr><tr><td><code>client_tags</code></td><td>no</td><td>Trino-internal tags for this connection.</td></tr></tbody></table>

#### OAuth (client credentials flow) properties

When `auth_type` is `OAuth2ClientCredentialsAuthentication`, configure the following nested properties under `oauth:`.

<table><thead><tr><th width="203.39996337890625">Property</th><th width="107.8333740234375">Required</th><th>Description</th></tr></thead><tbody><tr><td><code>oauth.token_url</code></td><td>yes</td><td>The OAuth 2.0 token endpoint to obtain an access token.</td></tr><tr><td><code>oauth.client_id</code></td><td>yes</td><td>OAuth 2.0 client identifier.</td></tr><tr><td><code>oauth.client_secret</code></td><td>yes</td><td>OAuth 2.0 client secret.</td></tr><tr><td><code>oauth.scope</code></td><td>no</td><td><p>Space-delimited, case-sensitive list of strings per <a href="https://www.rfc-editor.org/rfc/rfc6749#section-3.3">RFC 6749</a> (e.g., <code>"scope1 scope2"</code>).</p><p>No default value.</p></td></tr><tr><td><code>oauth.grant_type</code></td><td>no</td><td>OAuth 2.0 grant type. Leave unset to use the default <code>client_credentials</code>flow.</td></tr></tbody></table>

#### No authentication YAML

You can connect to a Trino data source without authentication:

```yaml
data_source my_trino:
  type: trino
  host: trino.example.com
  catalog: hive
  port: 8080
  http_scheme: http

  auth_type: NoAuthentication
```

## Test the data source connection <a href="#test-the-data-source-connection" id="test-the-data-source-connection"></a>

To confirm that you have correctly configured the connection details for the data source(s) in your configuration YAML file, use the `test-connection` command. If you wish, add a `-V` option to the command to return results in verbose mode in the CLI.

```sh
soda test-connection -d my_datasource -c configuration.yml -V
```
