Data Catalog

Note: The original feature called Shared Buckets is now integrated into our Data Catalog.

The data catalog represents an overview of data shared to and from the project. There are generally numerous options to share data (ranging from CSV exports to writing to a dedicated database). The data catalog allows you to share data in a very efficient, controlled and auditable way.


Sharing data via the data catalog is useful in numerous ways – for example:

  • You want to share the results of your analysis with another department. Instead of exporting it to CSV, you can simply share the data with their project. They will gain instant access to the selected data and can, e.g., load it into their sandbox immediately. The data is live, so whenever you update the results, your colleagues will see the changes.
  • You want to share some data with a data-processing contractor. Instead of exporting the data to CSV, you can create a new Keboola Connection project for them and share the data into that project. They will get immediate access to the selected data and can start working instantly. They can also share the results of their work with you the same way.
  • You need to provide your company with a set of curated data in auxiliary tables. You can have changing product names and instead of distributing updates throughout your company, you can create a project with the product table shared to the rest of the company. Regardless of how and how often the table is updated, this ensures that everyone always looks at the same data.
  • You might want to use Multi-project architecture.

The following terminology is used:

  • Shared bucket — source project bucket with Sharing enabled; it contains data to be available in other projects.
  • Linked bucket — reference to a shared bucket in any of the destination projects.

All changes and events in a shared bucket are propagated to its linked buckets; any tables you create in the shared bucket become immediately available in the destination projects. Data size and rows are counted only in the source project.

There are some constraints to how shared buckets can be used:

  • Source and destination projects must belong to the same organization (and region).
  • To manage shared buckets, your user account must be an organization member or a project administrator with the share role assigned.
  • Table aliases filtered by a condition are not shared.
  • Table aliases without automatically synchronized columns are not shared.
  • Tables in linked buckets work like aliases — i.e., all tables are read-only in the destination project.
  • If your bucket is already linked in other projects, you cannot drop it. Nor can you drop any of its children, tables or columns.
  • You cannot delete a shared bucket that has been linked, all the links need to be removed first.

Sharing Types

There are several options how you can share data:

  • Project Members – To the entire organization. Any user of any project in the organization can link the data bucket.
  • Organization Members – To administrators of the organization. Any user of any project in the organization can link the data bucket provided that they are also an administrator of the organization.
  • Selected Projects – To specified projects. Any user of the listed projects in the organization can link the data bucket.
  • Selected Users – To specified users. Any listed users in the organization can link the data bucket.

Enable Sharing

To share data outside of your project, go to Catalog a click Share a bucket.

Screenshot -- Enable sharing

Next you can choose whether you want to share an existing bucket or create a new one. Both options are technically the same, the choice depends purely on whether you prepared the data in advance (an existing bucket) or not (create a new bucket).

Share an Existing Bucket

Choose the Share existing bucket option:

Then, select the bucket and a sharing type. Optionally, provide a description of the bucket so others know what to expect.

Screenshot -- Finish sharing

The bucket is shared and instantly available to other projects in the organization depending on the sharing type you have chosen.

To change a sharing type, go to the bucket detail page and click the Edit sharing button:

Choose the Select tables option:

Screenshot -- Enable Sharing Tables

Select the tables and/or buckets you want to share:

Screenshot -- Select Tables

Enter the bucket name and a sharing type. Optionally, enter the description:

Screenshot -- Select Tables

A new bucket will be created for you, the selected tables will be linked to it using aliases.

Screenshot -- Bucket Result

To change a sharing type, share the newly created bucket again. The newly selected sharing type will overwrite the old one.

You can link a shared bucket into your project from Shared with you page:

Screenshot -- Link Bucket Start

Enter a name of the bucket as you’d like to see it in the current project and Link the bucket:

Screenshot -- Link Bucket

You’ll see that the bucket is available in your project:

Screenshot -- Link Bucket Result

You can see the detail of the shared bucket in with a link to the source project (if you have access to it).
