Databricks is making the case, via its own blog on July 13, 2026, that Unity Catalog managed tables have matured into the connective tissue enterprises need to run one data estate across engines and clouds without ceding governance control. That’s the vendor’s framing for anyone tracking the catalog wars — Unity Catalog, Polaris, Glue, and assorted Iceberg REST implementations all competing to be the metadata layer that decides who reads what, and on whose terms.
Worth noting: this is a company blog, not an independent benchmark, and “interoperability” from the vendor that owns the catalog is a claim customers should pressure-test against actual multi-engine deployments before signing anything.
The company selling you the catalog is rarely the neutral party to judge how open it really is.
For data infrastructure buyers, the real question isn’t whether managed tables perform well inside Databricks — it’s whether a non-Databricks engine can read, write, and govern against the same tables without friction or a support contract. That’s the detail worth watching as Databricks and its rivals keep publishing their own scorecards on openness.
Unity Catalog was designed for interoperability at scale. Enterprises have the flexibility…
