- why not use tools outside of Databricks to manipulate files in managed tables or volumes directly?
Managed tables and volumes are stored in managed storage.
Managed tables always use the Delta table format. ❌ you can now read and write Managed Iceberg tables using Databricks or external Iceberg engines via Unity Catalog’s Iceberg REST Catalog API.
All Managed Tables automatically deliver best-in-class read performance and storage optimization using [[Predictive Optimization]].
