Domino Datasets Skill

Description

This skill helps users work with Domino Datasets - high-performance, versioned filesystem storage for data science projects.

Activation

Activate this skill when users want to:

• Create or manage Domino Datasets
• Work with dataset snapshots and versioning
• Share data between projects
• Access large datasets efficiently
• Understand dataset paths and mounting

What is a Domino Dataset?

A Domino Dataset is:

• High-performance storage: Network filesystem optimized for data science
• Versioned: Create snapshots for reproducibility
• Shareable: Access across projects
• Scalable: No file size or count limits
• Persistent: Data persists across executions

Creating a Dataset

Via Domino UI

1. Navigate to your project
2. Go to Data > Domino Datasets
3. Click Create New Dataset
4. Enter:
   • Name: Dataset name (e.g., training-data)
   • Description: What the dataset contains
5. Click Create

Via Python SDK

from domino import Domino

domino = Domino("project-owner/project-name")

# Create a new dataset
dataset = domino.datasets_create(
    name="training-data",
    description="Training data for classification model"
)

Dataset Paths

Dataset paths differ based on your project type. Domino has two project types with different mount structures.

DFS (Domino File System) Projects

DFS projects use /domino as the root:
