Can you give me some examples of Gremlin queries?
Sure! Here are a few examples of Gremlin queries:
g.V().hasLabel('person')
- Retrieves all vertices with the label 'person'.g.E().hasLabel('knows')
- Retrieves all edges with the label 'knows'.g.V().has('name', 'Alice').out('knows')
- Finds all people that Alice knows.What does the out
step do in Gremlin?
The out
step in Gremlin is used to traverse outgoing edges from a vertex. It retrieves all vertices that are connected to the starting vertex via outgoing edges.
Can you show me a query that counts the number of vertices?
Absolutely! You can use the following query to count the number of vertices:
g.V().count()
.
How can I filter vertices based on properties?
You can filter vertices by using the has
step. For example, g.V().has('age', 30)
retrieves all vertices where the 'age' property is 30.
