Sharing foreign Delta tables
Put foreign tables in Delta format, which Databricks reads straight from their source storage, inside a share.
Why it is worth watching
Sharing without copying first. Foreign schemas and tables in general no longer carry a label on the page; the Delta variant still does.
What Public Preview promises
Open to everyone and supported for production use, though it can still change. On by default, and an admin can turn it off.
| Who can use it | Everyone |
|---|---|
| Production use | Yes |
| Support | The support team |
| On by default | Yes, with an opt-out |
The definitions are Databricks' own, on its release types page. The label on this page is the one the feature's documentation states, last checked on 14 Sept 2026.
Where to read more
It is part of something we wrote up: Sharing data with OpenSharing — How a share, a provider and a recipient actually work: the two sharing protocols, bearer tokens against OIDC federation, sharing with history, and what cannot be shared.
