Tutorial: Workflow for Collaborative Data Updates Using DVC and GitHub¶
Introduction¶
Learning Objectives
Master the workflow for managing collaborative data updates in projects using Data Version Control (DVC) and GitHub. This tutorial is designed to provide a clear guide for teams to maintain consistency and synchronization in their data-driven projects.
Prerequisites¶
- Basic knowledge of DVC and GitHub.
- A project set up with DVC and connected to a GitHub repository.
Collaborative Update Scenario¶
Imagine a collaborative environment where dataset updates need to be synchronized across a team's local environments.
Step-by-Step Workflow Guide¶
1. Local Data Update¶
Updating Data Locally
- Action: Make changes to your dataset locally, such as adding or editing data.
2. Tracking Changes with DVC¶
Using DVC for Tracking
- Command: Run
dvc add <file_or_directory>
to track changes. - Result: The
.dvc
file is updated to reflect the new dataset state.
3. Committing and Pushing to GitHub¶
Syncing with GitHub
- Commit and Push: Update your Git repository with the new data version.
- Outcome: Changes are now in the GitHub repository.
4. Team Syncing Process¶
Team Members' Actions
- Git Pull: Team members pull the latest changes.
- DVC Pull: Synchronize the local data with the updated version in DVC remote storage.
- Consistency Achieved: Everyone works with the same data version.
Sync Mechanism Explained¶
- :octicons-cloud-upload-24: DVC Remote Storage: Stores the updated data, accessible to all team members.
- Local Data Sync:
dvc pull
ensures local data matches the remote version.
Ensuring Data Consistency¶
- Version Control with
.dvc
Files: Crucial for indicating the current data version. - Data Synchronization: Managed through DVC commands, while Git handles
.dvc
file version control.
Conclusion¶
Key Takeaway
Following this workflow allows teams to efficiently collaborate on data-driven projects, ensuring data consistency, reproducibility, and effective teamwork. It's an essential practice for maintaining project integrity and collaborative efficiency.
