Examining graphs

Graphs have characteristics that can be examined with a variety of commands.

Procedure

A list of all graphs can be retrieved with the following command:
```
system.graphs()
```
In Studio and Gremlin console, a list is retrieved, although the presentation is different. Here is a Gremlin console result:
```
==> food
==> test
```
A list of all graph and their attributes can be retrieved as well:
```
system.list()
```
```
==>Name: food_cql | Engine: Core | Replication: {replication_factor=1, class=org.apache.cassandra.locator.SimpleStrategy}
==>Name: food_classic | Engine: Classic | Replication: {class=org.apache.cassandra.locator.NetworkTopologyStrategy, SearchGraphAnalytics=1}
```
This result shows two different graphs, one with a Core engine and one with a Classic engine. The first listed graph was created without replication settings and defaulted to a replication factor of 1 and a SimpleStrategy.

To examine a particular graph, use the describe command:

system.graph('food').describe()

==>system.graph('food').ifNotExists().withReplication("{'class': 'org.apache.cassandra.locator.NetworkTopologyStrategy', 'SearchGraphAnalytics': '1'}").andDurableWrites(true).create()
