The Property Graph Data Source (PGDS) is used to read and write property graphs from and to an external storage
(e.g., a database system, a file system or an memory-based collections of graph data).
The Property Graph Data Source (PGDS) is used to read and write property graphs from and to an external storage

The PGDS is the main interface for implementing custom data sources for specific openCypher implementations

The Property Graph Data Source (PGDS) is used to read and write property graphs from and to an external storage (e.g., a database system, a file system or an memory-based collections of graph data).
The PGDS is the main interface for implementing custom data sources for specific openCypher implementations (e.g., for Apache Spark, etc.).
The (PGDS) is able to handle multiple property graphs and distinguishes between them using org.opencypher.okapi.api.graph.GraphNames. Furthermore, a PGDS can be registered at a org.opencypher.okapi.api.graph.CypherSession using a specific org.opencypher.okapi.api.graph.Namespace which enables accessing a org.opencypher.okapi.api.graph.PropertyGraph within a Cypher query.
