This topic describes how to create a crawler to collect metadata from an AnalyticDB for MySQL 3.0 data source to DataWorks. You can view the collected metadata on the Data Map page.

Prerequisites

An EMR cluster is associated with your workspace as a compute engine instance. For more information, see Associate an EMR compute engine instance with a workspace.

Limits

  • You cannot collect metadata across regions. You must create a crawler in the region where the source metadata resides to collect the metadata.
  • You must collect metadata over the Internet.
