3.1 Loading a Graph into the Graph Server (PGX) from a Property Graph View

You can load a graph into the graph server (PGX) from a property graph view by name.

You can use the following PgxSession method to load a graph from a property graph view by name:

readGraphByName(String name, GraphSource source)

The arguments used in the method are as follows:

• name: Name of the property graph view.
• source: Source for the graph. In this case, PG_VIEW.

The readGraphByName(String name, GraphSource source) method reads the property graph view metadata tables and internally generates the graph configuration to load the graph. You must have PGX_SESSION_NEW_GRAPH permission to use this API.

For example you can load the graph from a property graph view as shown:

• JShell
• Java
• Python

var pgview = session.readGraphByName("bankdataview", GraphSource.PG_VIEW)
$12 ==> PgxGraph[name=bankdataview,N=1000,E=5001,created=1625730942294]

PgxGraph graph = session.readGraphByName("bankdataview", GraphSource.PG_VIEW);
Graph: PgxGraph[name=bankdataview,N=1000,E=5001,created=1625732149262]

>>> graph = session.read_graph_by_name('bankdataview', 'pg_view')
>>> graph
PgxGraph(name: bankdataview, v: 1000, e: 5001, directed: True, memory(Mb): 0)
