Control data sources and share data across projects

Project Admin · Updated 8 Nov 2026

Connections belong to one project, and only its Project Admins create, edit or delete them. Projects don't share datasets or connections, so data moves between projects by sending it, not by reading it.

Control who adds data sources

To create a connection:

  1. Click Data in the left sidebar, then New dataset.
  2. In Where do you want to add data from?, choose Connectors (or open the Connections tab and click New Connection).
  3. Pick the source in the Connectors launcher and connect it.

Project Editors can then start datasets from it on the Connections tab. An Editor who tries to add a new source sees "New sources are added by this project's admins." and can click Copy a request to send you a note. Workspace Owners can add users to, and delete, any project. See Manage saved connections.

Share data between projects

Projects don't share datasets or connections, and a Join or Lookup can't read another project's views. Send the data across first:

NeedMethod
Regular sharing inside MammothA view in Project B ends its pipeline with Send to Dataset, pointed at a dataset in Project A. It sends new data each time the pipeline runs
Sharing through your own databaseProject B exports a view to a shared database (for example PostgreSQL or BigQuery); Project A connects to it, and a Dataset Refresh keeps it current
One-time transferSave a copy from Project B (the download icon), then upload it into Project A
Read-only accessShare a dashboard, a collection, or a Live link (Team and Pro)

Create connections in each project that needs them, use approved shared databases for exchange, and use read-only credentials for production systems.
