Domino datasets provide high-performance, versioned, and structured filesystem storage in Domino. With Domino Datasets, you can build several curated collections of data in one project, and share them with your fellow contributors across their projects.

A Domino Dataset is a collection of files that are available in user executions as a filesystem directory. These files can be used and shared as a file system directory. A Dataset always reflects the most recent version of the data. You can modify the contents of a Dataset through the Domino application or through workload executions, at any time.

To version the contents of a Domino Dataset, you can create a Snapshot with a read-only copy of the Dataset files at a given time. Snapshots are associated with the Dataset they version.

The following are the primary ways to interact with a Domino Dataset:

Work with Datasets local to your project.
Read from a shared Dataset you have mounted to your project.
