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:

​
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.

Requirements

​
Python Requirements

We have support for Python versions 3.9-3.11
To run the Exasol ingestion, you will need to install: 
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

​
2. Run with the CLI

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