In this section, we provide guides and references to use the Exasol connector.
Configure and schedule Exasol metadata and profiler workflows from the OpenMetadata UI:

* [Requirements](#requirements)
* [Metadata Ingestion](#metadata-ingestion)
* [Lineage](/connectors/ingestion/lineage)

## How to Run the Connector Externally

To run the Ingestion via the UI you'll need to use the OpenMetadata Ingestion Container, which comes shipped with
custom Airflow plugins to handle the workflow deployment.

If, instead, you want to manage your workflows externally on your preferred orchestrator, you can check
the following docs to run the Ingestion Framework **anywhere**.

<Columns cols={2}>
  <Card title="External Schedulers" href="/v1.12.x/deployment/ingestion">
    Get more information about running the Ingestion Framework Externally
  </Card>
</Columns>

## Requirements

### Python Requirements

<Tip>
  We have support for Python versions **3.9-3.11**
</Tip>

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

```bash theme={null}
pip3 install "openmetadata-ingestion[Exasol]"
```

### Database Privilege Requirements

To ingest basic metadata, an Exasol user must have the following privileges:

* `USAGE` privilege on Schema
* `SELECT` privilege on Tables

OpenMetadata fetches the query logs for the lineage workflow by querying `EXA_STATISTICS.EXA_DBA_AUDIT_SQL` table.
For this, an Exasol user should be granted the `SELECT ANY DICTIONARY` system privilege.

## Metadata Ingestion

### 1. Define the YAML Config

<CodePreview>
  <ContentPanel>
    <ContentSection id={1} title="Source Configuration" lines="1-3">
      Configure the source type and service name for your Exasol connector.
    </ContentSection>

    <ContentSection id={2} title="Username" lines="7">
      **username**: The username required to authenticate and connect to the Exasol database. The user must have sufficient privileges to access and read all the metadata available in Exasol.
    </ContentSection>

    <ContentSection id={3} title="Password" lines="8">
      **password**: The password associated with the user account used to connect to the Exasol database. Ensure this password corresponds to the specified username and is stored securely. Avoid sharing passwords in plain text and use secure methods for managing sensitive credentials.
    </ContentSection>

    <ContentSection id={4} title="Host Port" lines="9">
      **hostPort**: Provide the fully qualified hostname and port number of your Exasol deployment in the "Host and Port" field.
    </ContentSection>

    <ContentSection id={5} title="SSL/TLS Settings" lines="10">
      **SSL/TLS Settings**: Mode/setting for SSL validation:

      * **validate-certificate**: Uses Transport Layer Security (TLS) and validates the server certificate using system certificate stores.
      * **ignore-certificate**: Uses Transport Layer Security (TLS) but disables the validation of the server certificate. This should not be used in production. It can be useful during testing with self-signed certificates.
      * **disable-tls**: Does not use any Transport Layer Security (TLS). Data will be sent in plain text (no encryption). While this may be helpful in rare cases of debugging, make sure you do not use this in production.
    </ContentSection>

    <ContentSection id={6} title="Connection Options" lines="11">

### 2. Run with the CLI

First, we will need to save the YAML file. Afterward, and with all requirements installed, we can run:

```bash theme={null}
metadata ingest -c <path-to-yaml>
```

Note that from connector to connector, this recipe will always be the same. By updating the YAML configuration,
you will be able to extract metadata from different sources.
