Delta inside the Nexus ecosystem

Delta can be used as a store for Nexus Forge and works seamlessly with Nexus Fusion. We offer several clients that consume the API of Delta. Nexus.js allows you to build data-driven web applications, Nexus Python SDK to integrate your data pipelines with the Knowledge Graph and the Nexus CLI allows you to manage your deployment from the command line.

All data and metadata stored into your Knowledge Graph is versioned. All metadata is further indexed into views that offer several access modalities such as Graph and Document.
