How to use graph data type using by pl/python in AgensGraph?

Question

I am using AgensGraph.
I know the PostgreSQL supports pl/python driver.
So I think the AgensGraph supports it, too.
If I want to use a graph data type using by pl/python, is the way same with general data?

Answer 1

In order to use PL/Python in AgensGraph you need to Create the plpythonu language.

A good example for PL/Python in AgensGraph would be as following:

Enabling the module

CREATE LANGUAGE plpythonu;

Creating sample data

CREATE (a:person {id:1,name:'Bob'});

Creating PL/Python function

CREATE OR REPLACE FUNCTION firstname()
RETURNS void
AS $$
#Python source code starts
records = plpy.execute("MATCH (a:person) RETURN a.name AS sample")
plpy.info(records[0]['sample'])
#Python source code ends
$$ LANGUAGE plpythonu;

Calling the function

SELECT firstname();
