case class CommunityNeo4jGraphDataSource(config: Neo4jConfig, queries: Map[GraphName, (String, String)] = ..., schemata: Map[GraphName, Schema] = Map.empty)(implicit session: CAPSSession) extends CAPSPropertyGraphDataSource with Product with Serializable

A data source implementation that enables loading property graphs from a Neo4j database. A graph is identified by a GraphName and parameterized by a node and a relationship query which are used to load the graph from Neo4j.

If the Schema of a Neo4j graph is known upfront, it can be provided to the data source. Otherwise, the schema will be computed during graph loading.

config

queries

schemata
