Data sharing¶

Publish data from this workspace’s Catalog to specified workspaces for them to subscribe to. Sharing uses a “publish → subscribe” model and does not provide public links; you must specify a target workspace when publishing.

Entry point: Resource Center → Data Sharing → Publish. For subscriber-side operations, see Data subscriptions.

Publish and subscribe model¶

Side	Who	What they do
Publisher	Data owner	Select objects from Catalog and specify target workspaces, permissions, and validity periods
Subscriber	Data consumer	Subscribe to received publications; the data enters their Catalog as a read-only “subscribed library”

A subscribed library always points to the source data maintained by the publisher. Subscribers see updates to the source; access ends when the publication is revoked or expires. This does not create two independent sources of truth.

Add a publication¶

Go to Resource Center → Data Sharing, open the Publish tab, and click Add Publication.
Enter a publication name (required).
Select one publication object in the Catalog tree: catalog, database, volume, or table (models and operators are excluded).
Specify one or more publication targets:
- Select another workspace under the same account from the list; or
- Enter a workspace ID to add a workspace under another account.
Set publication permissions and a validity period, and optionally enter a note.
Confirm the publication.

Field	Description
Publication name	Name of this publication
Publication object	A catalog, database, volume, or table in Catalog
Publication target	One or more target workspaces
Publication permission	Read-only or downloadable (see below)
Validity period	Permanent or a specified expiration date
Note	Optional description

Publication permissions¶

Permission	What subscribers can do
Read-only	Query and preview, but cannot download or export
Downloadable	Download or export in addition to read-only access

Subscribed libraries are never writable, regardless of the permission. Prefer read-only access for sensitive data.

View and manage publications¶

The Publish tab lists published data and supports searches by publication name, object, or target.

Operation	Description
Edit	Modify the name, object, target, permission, validity period, or note
Delete	Revoke the publication; target workspaces can no longer access the data

Access statistics¶

Publishers can view access counts, most recent access time, and similar statistics in a publication record to evaluate the value of sharing.

Usage notes¶

After publication, the recipient must actively subscribe from the Subscribe side before using the data.
When publishing at database level, later additions or removals within the database may also appear in the subscriber’s view.
Before publishing across accounts, carefully verify the recipient’s workspace ID.
Deleting a publication only stops subsequent access. Data that the recipient already exported under the Downloadable permission is outside platform control.
A publication is a read-only view of source data, not a frozen snapshot. If you need a fixed version, materialize it as a separate object before publishing.
