AWS Glue OCF Connector: Overview¶
Alation Cloud Service Applies to Alation Cloud Service instances of Alation
Customer Managed Applies to customer-managed instances of Alation
The OCF connector for AWS Glue was developed by Alation and is available as a Zip file that can be uploaded and installed in the Alation application.
To download the AWS Glue OCF connector package, go to the Alation Connector Hub available from the Customer Portal. Go to Customer Portal > Connectors > Alation Connector Hub. Only Alation users with access to the Customer Portal can access the Alation Connector Hub. If you don’t have access to the Customer Portal, contact Alation Support.
This connector should be used to catalog AWS Glue as a data source on Alation on-prem and Cloud Service instances. It uses the AWS Glue API to connect to your AWS Glue instance and extract metadata. The connector is compiled with all necessary libraries to make API calls to AWS. No separate code or drivers are required. After the metadata is extracted, it is represented in the data catalog as a hierarchy of catalog pages under the parent data source. Alation users can leverage the full catalog functionality to search for and find the metadata, curate the corresponding catalog pages, enrich the catalog with documentation about the data source, and exchange information with other catalog users.
