Your data, your storage, your rules: a 2026 guide to storing Unity Catalog managed tables

Unity catalog managed tables allow you to control the placement of your data when your organization needs separate storage. Unlike other data platforms, Databricks table data remains in a cloud storage account that you own such as your S3 bucket, your ADLS container, or your GCS bucket. 

Unity Catalog managed tables automate table management. Whether you store your Unity Catalog managed tables in Iceberg or Delta formats, Databricks handles the data layout, tuning, and cleanup for you where you choose, applying optimizations automatically as your tables change. 

This blog explains how the managed tables storage model works, and how you can choose or change a Databricks managed storage location. 

When you bring your own cloud storage, managed table data lands in a cloud account you own. You keep ownership of that storage and visibility into how your data is organized. You have the ability to inspect, audit and apply our own bucket policies, as well as control the location of your data. 

Unlike other platforms with managed or native table offerings that hold tables in provider-controlled storage or proprietary data formats, at Databricks, your data stays in your own account.
