Introduction to Google Looker catalog sources

You can use Metadata Command Center to extract metadata from a source system.
A source system is any system that contains data or metadata. For example, Google Looker is a source system from which you can extract metadata through a Google Looker catalog source with Metadata Command Center. A catalog source is an object that represents and contains metadata from the source system.
Before you extract metadata from a source system, you first create and register a catalog source that represents the source system.
When Metadata Command Center extracts metadata, Data Governance and Catalog displays the extracted metadata and its attributes as technical assets. You can then perform tasks such as analyzing the assets, viewing lineage, and creating links between those assets and their business context.
The following table describes the capabilities of the catalog source:

Description
Serverless Runtime Environment
A serverless runtime environment is an advanced serverless deployment solution that doesn't require downloading, installing, configuring, or maintaining a Secure Agent or Secure Agent group. You can use a serverless runtime environment in the same way that you use a Secure Agent when you configure a catalog source.

Extraction and view process

To extract metadata from a source system, configure the catalog source and run the extraction job in Metadata Command Center. Then view the results in Data Governance and Catalog
The following image shows the process to extract metadata from a source system:
The image shows the process of metadata extraction from a Google Looker source system that begins with prerequisites verification, continues with the creation of the catalog source, and ends with viewing the results and lineage.
After you verify prerequisites, perform the following tasks to extract metadata from Google Looker:
  1. 1Register a catalog source. Create a catalog source object, select the source system, and specify values for connection properties.
  2. 2Configure the catalog source. Specify the runtime environment, optionally override secure authentication strings, and add filters.
  3. 3Associate stakeholders. Optionally, associate users with technical assets, giving the users permission to perform actions determined by their roles.
  4. 4Run or schedule the catalog source job.
  5. 5Assign a connection to referenced source system assets.
