Nodestream

A Declarative framework for Building, Maintaining, and Analyzing Graph Data 🚀

Nodestream allows you to work with graphs declaratively. With nodestream, you unlock a bounty of features purpose built for working with graphs. Semantically model your graph and map labels and properties directly to your data. Better yet, you are not locked into your choices. Nodestream works with you as you evolve your application by providing migration utilities to change your data schema. Nodestream even decouples you from the underyling database technology so you can even change databases.

Highlights

• Connect to data sources like Kafka, files, apis, and more!
• Evolve your application over time with database migrations (Docs)
• Use your favorite Graph Database to fit any tech stack (Docs)
• Clean up your own data with TTLs (Docs)
• Infinite Customizability Since Nearly Everything is Pluggable!
