Interactive Query

class graphscope.interactive.query.InteractiveQuery(interactive_query_node=None, frontend_endpoint=None, object_id=None)

InteractiveQuery class, is a simple wrapper around Gremlin-Python, which implements Gremlin within the Python language. It also can expose gremlin endpoint which can be used by any other standard gremlin console, with the method graph_url().

It also has a method called subgraph which can extract some fragments from origin graph, produce a new, smaller but concise graph stored in vineyard, which lifetime is independent from the origin graph.

User can either use execute() to submit a script, or use traversal_source() to get a GraphTraversalSource for further traversal.

__init__(interactive_query_node=None, frontend_endpoint=None, object_id=None)

Construct a InteractiveQuery object.

close()

Close interactive instance and release resources

closed()

Return if the current instance is closed.

property error_msg

execute(query, request_options=None)

property graph_url

The gremlin graph url can be used with any standard gremlin console, e.g., tinkerpop.

property object_id

property status

subgraph(gremlin_script, request_options=None)

traversal_source()

Create a GraphTraversalSource and return. Once g has been created using a connection, we can start to write Gremlin traversals to query the remote graph.

Raises

RuntimeError – If the interactive script is not running.

Examples

sess = graphscope.session()
graph = load_modern_graph(sess, modern_graph_data_dir)
interactive = sess.gremlin(graph)
g = interactive.traversal_source()
print(g.V().both()[1:3].toList())
print(g.V().both().name.toList())

Returns

GraphTraversalSource
