How Python Data Engineers Use OrientDB

Python data engineers use `pyorient` to connect to OrientDB and run graph queries alongside document operations. A common use case is building knowledge graph pipelines — ingesting entity documents and their relationships, querying multi-hop connections to discover related entities, and exporting subgraphs for ML feature engineering.
