**Description:** - **Memgraph** no longer relies on `Neo4jGraphStore` but **implements `GraphStore`**, just like other graph databases. - **Memgraph** no longer relies on `GraphQAChain`, but implements `MemgraphQAChain`, just like other graph databases. - The refresh schema procedure has been updated to try using `SHOW SCHEMA INFO`. The fallback uses Cypher queries (a combination of schema and Cypher) → **LangChain integration no longer relies on MAGE library**. - The **schema structure** has been reformatted. Regardless of the procedures used to get schema, schema structure is the same. - The `add_graph_documents()` method has been implemented. It transforms `GraphDocument` into Cypher queries and creates a graph in Memgraph. It implements the ability to use `baseEntityLabel` to improve speed (`baseEntityLabel` has an index on the `id` property). It also implements the ability to include sources by creating a `MENTIONS` relationship to the source document. - Jupyter Notebook for Memgraph has been updated. - **Issue:** / - **Dependencies:** / - **Twitter handle:** supe_katarina (DX Engineer @ Memgraph) Closes #25606 |
