In this section, we provide guides and references to use the GCS Datalake connector.
Configure and schedule GCS Datalake 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
Note: GCS Datalake connector supports extracting metadata from file types JSON, CSV, TSV & Parquet.
Python Requirements
We have support for Python versions 3.9-3.11
If running OpenMetadata version greater than 0.13, you will need to install the Datalake ingestion for GCS
GCS installation
pip3 install "openmetadata-ingestion[datalake-gcp]"
If version <0.13
You will be installing the requirements for GCS
pip3 install "openmetadata-ingestion[datalake]"
All connectors are defined as JSON Schemas. Here you can find the structure to create a connection to Datalake.
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.
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.
