Roadmap

Renamed: This project was renamed from Deveel.Repository to Kista on May 26, 2025. The name Kista is Old Norse for "chest" or "repository", better reflecting the project purpose as a data access framework.

The Kista framework provides a pragmatic, DDD-aligned abstraction for multi-source data access in .NET. Below is the planned roadmap of future releases.

See the full roadmap for detailed feature descriptions, timelines, and architectural decisions.

  • Service-Based Repository Driver: RESTful and gRPC service-backed repository implementation.
  • Neo4j Repository Driver: A graph database repository driver built on the Neo4j .NET driver.

Success Metrics​

Each milestone release is considered successful when:

  • All public APIs carry 100% XML documentation coverage — enforced in CI
  • Test coverage ≥ 85% on Core and Manager packages
  • No performance regressions vs. the previous milestone BenchmarkDotNet baseline
  • A migration guide is published before the release NuGet packages land
  • Zero P1 bug reports within 30 days of release
