About

Data Versioning

Purpose

Track dataset and model versions to ensure reproducibility and maintain data lineage.

How It Works

Tool Selection

| Tool | Best For | Storage | |------|----------|---------| | DVC | Git-based, ML projects | S3, GCS, local | | LakeFS | Data lake versioning | S3-compatible | | Delta Lake | Spark/Databricks | Cloud storage | | Git LFS | Small binary files | Git remote |

DVC Workflow

  1. Initialize DVC in your git repo
  2. Track data files with dvc add
  3. Push data to remote storage
  4. Version with git commits
  5. Reproduce with dvc repro

Best Practices

  • Never commit large data to git
  • Tag important data versions (training sets, releases)
  • Document data changes in commit messages
  • Automate data validation on version changes

Usage Examples

"Set up DVC to version our training datasets stored on S3"

Output Format

  • Setup Guide: Tool installation and configuration
  • Workflow: How to version, retrieve, and compare data
  • Python Code: Programmatic versioning integration
