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
.
