The journey continues. Genesis DB - just got a serious upgrade.

What’s New in 0.0.6?

Say hello to Preconditions and Schema Registration - powerful new features designed to enforce data integrity, guard against invalid inputs, and streamline your development flow.

Preconditions: Smarter Commits, Built In

Preconditions act as gatekeepers that validate business logic before data gets written. The first available precondition (isSubjectNew) checks whether a subject already has events or if it's brand new.

Why it matters:

• Avoid conflicts: Prevent accidental overwrites or duplicate inits
• Enforce rules: Business logic enforced at the database layer
• Fail fast: Catch invalid state transitions before they become problems

Schema Registration: Built-In Validation

You can now register data schemas in Genesis DB. Once defined, every incoming event is automatically validated against its schema. No more surprises.

What it gives you:

• Type safety: Ensure your event data matches the expected structure
• Data consistency: Keep your event stream clean and predictable
• Less boilerplate: No need to write custom validators - it's automatic
• Confidence in your data: Invalid payloads are rejected before they hit storage

Why This Update Matters

Genesis DB now does more than store events - it helps protect your system from the inside out. With preconditions and schema validation, your data pipeline becomes more resilient, reliable, and developer-friendly.

Try It Now

These features are available starting in Genesis DB 0.0.6. Define your schemas. Enable your rules. Build with confidence.
