Ingestion Deployment

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 you want to install it manually in an already existing Airflow host, you can follow this guide.

If you don't want to use the OpenMetadata Ingestion container to configure the workflows via the UI, then you can check the following docs to run the Ingestion Framework in any orchestrator externally.

Requirements

To ingest basic metadata snowflake user must have the following privileges:

• USAGE Privilege on Warehouse
• USAGE Privilege on Database
• USAGE Privilege on Schema
• SELECT Privilege on Tables

• Incremental Extraction: Openmetadata fetches the information by querying snowflake.account_usage.tables.

• Ingesting Tags: Openmetadata fetches the information by querying snowflake.account_usage.tag_references.

• Lineage & Usage Workflow: Openmetadata fetches the query logs by querying snowflake.account_usage.query_history table. For this the snowflake user should be granted the ACCOUNTADMIN role or a role granted IMPORTED PRIVILEGES on the database SNOWFLAKE.

You can find more information about the account_usage schema here.

• Ingesting Stored Procedures: Openmetadata fetches the information by querying snowflake.account_usage.procedures & snowflake.account_usage.functions.

Metadata Ingestion

1. Visit the Services Page

Click Settings in the side navigation bar and then Services.

The first step is to ingest the metadata from your sources. To do that, you first need to create a Service connection first.

This Service will be the bridge between OpenMetadata and your source system.

Once a Service is created, it can be used to configure your ingestion workflows.

Select your Service Type and Add a New Service

2. Create a New Service

Click on Add New Service to start the Service creation.

Add a new Service from the Services page

3. Select the Service Type

Select Snowflake as the Service type and click Next.

Select your Service from the list

4. Name and Describe your Service

Provide a name and description for your Service.

Service Name

OpenMetadata uniquely identifies Services by their Service Name. Provide a name that distinguishes your deployment from other Services, including the other Snowflake Services that you might be ingesting metadata from.

Note that when the name is set, it cannot be changed.

Provide a Name and description for your Service

5. Configure the Service Connection

In this step, we will configure the connection settings required for Snowflake.

Please follow the instructions below to properly configure the Service to read from your sources. You will also find helper documentation on the right-hand side panel in the UI.
