What is Data Versioning?
Data Versioning is the practice of tracking and managing different versions of datasets used in machine learning, similar to code versioning. It enables reproducibility, facilitates collaboration, supports rollback, and ensures that models can be retrained with exactly the same data used in original development.
This glossary term is currently being developed. Detailed content covering implementation strategies, best practices, and operational considerations will be added soon. For immediate assistance with AI implementation and operations, please contact Pertama Partners for advisory services.
Data versioning eliminates the 'which data was this model trained on' problem that causes 20-30% of ML debugging time and blocks reproducibility audits. Organizations with data versioning resolve data-related model issues 5x faster by quickly comparing dataset versions to identify when problems were introduced. For regulated industries in Southeast Asia, data versioning provides the provenance documentation that financial and healthcare regulators require for automated decision systems. The investment in versioning infrastructure (typically free open-source tools plus storage costs) prevents the costly situation where models cannot be retrained to match previous performance because the original training data state was lost.
- Efficient storage using deduplication and delta compression
- Snapshot-based or incremental versioning strategies
- Integration with experiment tracking and model registry
- Performance optimization for large-scale datasets

For teams under 10 with file-based datasets (CSV, Parquet, images): DVC (Data Version Control) integrates with Git workflows and supports S3, GCS, and Azure storage backends with zero licensing cost. For teams working with large-scale structured data: Delta Lake or Apache Iceberg provide table-level versioning with time travel queries integrated into Spark and data warehouse workflows. For teams needing lightweight versioning: LakeFS provides Git-like branching for data lakes with minimal setup. For image and video datasets: Pachyderm combines data versioning with pipeline tracking. Choose based on data size and format: DVC for datasets under 100GB, Delta Lake for structured data at any scale, LakeFS for mixed workloads. Start with DVC if unsure, as migration to more sophisticated tools is straightforward.
Follow a four-step migration over 2-3 weeks: Step 1 snapshot current training datasets and tag them as baseline versions in your chosen versioning tool. Step 2 integrate version references into experiment tracking (log the dataset version ID with every experiment run in MLflow or W&B). Step 3 modify data pipelines to automatically create new versions when data is refreshed, adding metadata including row counts, schema hash, and data quality scores. Step 4 update model documentation to reference specific dataset versions for reproducibility. Don't attempt to retroactively version historical datasets unless needed for regulatory compliance. Focus on ensuring all future data changes are captured. The most common mistake is over-engineering versioning for data that rarely changes; apply versioning proportional to data volatility.

A TPU, or Tensor Processing Unit, is a custom-designed chip built by Google specifically to accelerate machine learning and AI workloads, offering high performance and cost efficiency for training and running large-scale AI models, particularly within the Google Cloud ecosystem.
A model registry is a centralised repository for storing, versioning, and managing machine learning models throughout their lifecycle, providing a single source of truth that tracks which models are in development, testing, and production across an organisation.
A feature pipeline is an automated system that transforms raw data from various sources into clean, structured features that machine learning models can use for training and prediction, ensuring consistent and reliable data preparation across development and production environments.
An AI gateway is an infrastructure layer that sits between applications and AI models, managing routing, authentication, rate limiting, cost tracking, and failover to provide centralised control and visibility over all AI model interactions across an organisation.
Model versioning is the practice of systematically tracking and managing different iterations of AI models throughout their lifecycle, recording changes to training data, parameters, code, and performance metrics so teams can compare, reproduce, and roll back to any previous version.
