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

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

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

## Requirements

### Python Requirements

{% partial file="/v1.5/connectors/python-requirements.md" /%}

To run the Presto ingestion, you will need to install:

```bash
pip3 install "openmetadata-ingestion[presto]"
```

## Metadata Ingestion

All connectors are defined as JSON Schemas.
[Here](https://github.com/open-metadata/OpenMetadata/blob/main/openmetadata-spec/src/main/resources/json/schema/entity/services/connections/database/prestoConnection.json)
you can find the structure to create a connection to Presto.

In order to create and run a Metadata Ingestion workflow, we will follow
the steps to create a YAML configuration able to connect to the source,
process the Entities if needed, and reach the OpenMetadata server.

The workflow is modeled around the following
[JSON Schema](https://github.com/open-metadata/OpenMetadata/blob/main/openmetadata-spec/src/main/resources/json/schema/metadataIngestion/workflow.json)

### 1. Define the YAML Config

This is a sample config for Presto:

{% codePreview %}

{% codeInfoContainer %}

#### Source Configuration - Service Connection

{% codeInfo srNumber=1 %}
**Username**: Specify the User to connect to Presto. It should have enough privileges to read all the metadata.

{% /codeInfo %}

{% codeInfo srNumber=2 %}

**password**: Password to connect to Presto.

{% /codeInfo %}

{% codeInfo srNumber=3 %}

**hostPort**: Enter the fully qualified hostname and port number for your Presto deployment in the Host and Port field.

{% /codeInfo %}

{% codeInfo srNumber=4 %}

**catalog**: Presto offers a catalog feature where all the databases are stored.

{% /codeInfo %}

{% codeInfo srNumber=5 %}

**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.

{% /codeInfo %}

{% partial file="/v1.5/connectors/yaml/ingestion-sink-def.md" /%}

{% partial file="/v1.5/connectors/yaml/workflow-config-def.md" /%}

#### Advanced Configuration

{% codeInfo srNumber=6 %}

**Connection Options (Optional)**: Enter the details for any additional connection options that can be sent to database during the connection. These details must be added as Key-Value pairs.

{% /codeInfo %}

{% codeInfo srNumber=7 %}

**Connection Arguments (Optional)**: Enter the details for any additional connection arguments such as security or protocol configs that can be sent to database 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"`

{% /codeInfo %}

{% /codeInfoContainer %}

{% codeBlock fileName="filename.yaml" %}

```yaml {% isCodeBlock=true %}
source:
  type: presto
  serviceName: local_presto
  serviceConnection:
    config:
      type: Presto
      scheme: presto
```
```yaml {% srNumber=1 %}
      username: user
```
```yaml {% srNumber=2 %}
      password: password
```
```yaml {% srNumber=3 %}
      hostPort: localhost:8080
```
```yaml {% srNumber=4 %}
      catalog: catalog
```
```yaml {% srNumber=5 %}
      databaseSchema: schema
```
```yaml {% srNumber=6 %}
      # connectionOptions:
      #   key: value
```
```yaml {% srNumber=7 %}
      # connectionArguments:
      #   key: value
```
