Zed.dev launches DeltaDB, a version‑aware data store

Zed.dev announced DeltaDB, a version‑aware data store that persists and queries changes between commits [Zed.dev Blog]. The store sits between Git‑style version control and relational databases, exposing an API that lets developers retrieve the exact set of file modifications for any commit range.

Core capabilities

• Commit‑aware schema that records each change as a first‑class record.
• Query operators that filter by commit, path, or change type, enabling selective test runs.
• Integration hooks for CI systems such as GitHub Actions, allowing pipelines to fetch only the files that actually changed.

By exposing only the delta between revisions, DeltaDB cuts the time spent rebuilding full test suites and eliminates unnecessary data movement in ETL jobs. Early adopters report up to a 40 % reduction in CI job duration when they replace full checkout steps with DeltaDB queries [Zed.dev Blog].

The product is available as an open‑source library with Docker images and a managed SaaS offering. Documentation includes a quick‑start guide for wiring DeltaDB into a typical CI workflow and examples of using the store to version data assets in a data‑lake pipeline.

Overall, DeltaDB gives teams a concrete mechanism to treat code and data changes as first‑class entities, tightening the feedback loop between commit and deployment.
