DataStax RAGStack Knowledge Graph
Project description
RAGStack Knowledge Store
[!WARNING] This is a proof-of-concept showing how knowledge graphs can be stored in Astra / Cassandra and retrieved via traversal. There are a variety of planned improvements including benchmarking, evaluation, and possible schema changes.
This includes some code (CassandraGraphStore) which could be added to
LangChain or RAGStack to write LangChain's GraphDocuments to Cassandra tables.
It also includes code to create a runnable for retrieving knowledge triples from
Cassandra.
The file notebook.ipynb shows this working on an example snippet from
LangChain's docs.
To run, copy env.template to .env.
