What is Databricks Lakehouse Federation?
Databricks Lakehouse Federation is essentially a data virtualization layer that allows you to query data across multiple data sources without actually moving the data. Think of it as a universal translator for your data. Instead of having all your data locked away in different silos, the Lakehouse Federation lets you access and analyze it as if it were all in one place. This includes databases like MySQL, PostgreSQL, Snowflake, and even other Databricks workspaces. The beauty of this approach is that you don't have to go through the painful process of ETL (Extract, Transform, Load) to consolidate your data. This saves you time, resources, and a whole lot of headaches.
The core idea behind Databricks Lakehouse Federation is to provide a unified view of your data, regardless of where it's stored. It achieves this by creating a metadata layer that understands the structure and semantics of the data in each source. When you run a query, the Lakehouse Federation optimizes the query execution by pushing down operations to the source systems whenever possible. This means that the data processing happens where the data resides, minimizing data transfer and maximizing performance. Moreover, it supports various data governance and security policies consistently across all federated data sources, ensuring data privacy and compliance. This is particularly important for organizations dealing with sensitive data and regulatory requirements.
