In this section, we provide guides and references to use the Trino connector.

Configure and schedule Trino metadata and profiler workflows from the OpenMetadata UI:

- [Requirements](#requirements)
- [Metadata Ingestion](#metadata-ingestion)
- [Data Profiler](/connectors/ingestion/workflows/profiler)
- [Data Quality](/connectors/ingestion/workflows/data-quality)
- [dbt Integration](/connectors/ingestion/workflows/dbt)

{% partial file="/v1.2.0/connectors/ingestion-modes-tiles.md" variables={yamlPath: "/connectors/database/trino/yaml"} /%}

## Requirements

### Metadata

To extract metadata, the user needs to be able to have `SELECT` permission to the following tables:
- `information_schema.schemata`
- `information_schema.columns`
- `information_schema.tables`
- `information_schema.views`
- `system.metadata.table_comments`

Access to resources will be based on the user access permission to access specific data sources. More information regarding access and security can be found in the Trino documentation [here](https://trino.io/docs/current/security.html).

### Profiler & Data Quality

Executing the profiler workflow or data quality tests, will require the user to have `SELECT` permission on the tables/schemas where the profiler/tests will be executed. More information on the profiler workflow setup can be found [here](https://docs.open-metadata.org/connectors/ingestion/workflows/profiler) and data quality tests [here](https://docs.open-metadata.org/connectors/ingestion/workflows/data-quality).

## Metadata Ingestion

}

#### Connection Details

- **Username**: Specify the User to connect to Trino. It should have enough privileges to read all the metadata.
- **Password**: Password to connect to Trino.
- **Host and Port**: Enter the fully qualified hostname and port number for your Trino deployment in the Host and Port field.
- **Catalog**: Trino offers a catalog feature where all the databases are stored. (Providing the Catalog is not mandatory from 0.12.2 or greater versions)
- **DatabaseSchema**: DatabaseSchema of the data source. This is optional parameter, if you would like to restrict the metadata reading to a single databaseSchema. When left blank, OpenMetadata Ingestion attempts to scan all the databaseSchema.
- **proxies**: Proxies for the connection to Trino data source
- **params**: URL parameters for connection to the Trino data source
- **Connection Options (Optional)**: Enter the details for any additional connection options that can be sent to Trino during the connection. These details must be added as Key-Value pairs.
- **Connection Arguments (Optional)**: Enter the details for any additional connection arguments such as security or protocol configs that can be sent to Trino during the connection. These details must be added as Key-Value pairs. 
  - In case you are using Single-Sign-On (SSO) for authentication, add the `authenticator` details in the Connection Arguments as a Key-Value pair as follows: `"authenticator" : "sso_login_url"`


**SSL Configuration**

In order to integrate SSL in the Metadata Ingestion Config, the user will have to add the SSL config under **connectionArguments** which is placed in source.

**SSL Modes**
There are a couple of types of SSL modes that redshift supports which can be added to ConnectionArguments, they are as follows:
- **false**: In order to disable SSL verification, set the `verify` parameter to `False`.
- **\<path-to-crt\>**: To use self-signed certificates, specify a path to the certificate in `verify` parameter.
Find more details in [the Python requests library documentation](https://requests.readthedocs.io/en/latest/user/advanced/#ssl-cert-verification).
