Getting Started

This guide will take you through starting a graph based on provided data.


This tutorial requires you to be connected to local Cayley installation. For more information on installing Cayley locally, see Install Cayley.

Start Cayley

cayley http
You should see:
Cayley version: 0.7.7 (dev snapshot)
using backend "memstore"
listening on, web interface at
You can now open the web-interface on: localhost:64210.
Cayley is configured by default to run in memory (That's what backend memstore means). To change the configuration see the documentation for Configuration File or run cayley http --help.
For more information about the UI see: UI Overview

Run with sample data

Download sample data

Run Cayley

cayley http --load 30kmoviedata.nq.gz

Query Data

Using the 30kmoviedata.nq dataset from above, let's walk through some simple queries:

Query all vertices in the graph

To select all vertices in the graph call, limit to 5 first results. g and V are synonyms for graph and Vertex respectively, as they are quite common.

Match a property of a vertex

Find vertex with property "Humphrey Bogart"
.has("<name>", "Humphrey Bogart")
You may start to notice a pattern here: with Gizmo, the query lines tend to:
Start somewhere in the graph | Follow a path | Run the query with "all" or "getLimit"

Match a complex path

Get the list of actors in the film
.has("<name>", "Casablanca")


This is starting to get long. Let's use a Morphism, a pre-defined path stored in a variable, as our linkage
var filmToActor = g
.has("<name>", "Casablanca")
