Unity Catalog in Databricks
The Unity Catalog is a feature in Databricks that allows users to manage and organize their data assets within the platform. It provides a unified view of various data sources, making it easier for users to discover, access, and analyze their data.
The Unity Catalog enables users to register different types of data assets such as tables, views, databases, and files. These assets can be sourced from various locations including cloud storage systems like Amazon S3 or Azure Blob Storage, on-premises databases like MySQL or Oracle Database, or other external services.
Once registered in the Unity Catalog, these data assets can be easily accessed by multiple users across different workspaces within Databricks. This promotes collaboration and eliminates the need for duplicating or moving datasets between environments.
