AnzoGraph vs Graphwise GraphDB (Ontotext)

AnzoGraph: MPP in-memory RDF graph database for OLAP-style SPARQL analytics, now Altair Graph Lakehouse under Siemens. Graphwise GraphDB (Ontotext): Standards-compliant RDF triplestore with reasoning, connectors and MCP support for GraphRAG.

key differences

  • AnzoGraph is built for larger datasets (≤ 1 PB) than Graphwise GraphDB (Ontotext) (≤ 10 TB).
  • Horizontal scaling is native in AnzoGraph and none in Graphwise GraphDB (Ontotext).
  • Transactions: AnzoGraph offers limited ACID; Graphwise GraphDB (Ontotext) offers full.
  • Only AnzoGraph has joins, in-memory.
  • Only Graphwise GraphDB (Ontotext) has transactions, full-text search, vector search, encryption at rest, role-based access.
