Creating a graph in DataStax Studio.
Depending on the DSE Graph schema mode, DataStax Studio will have differing behavior.
In Production mode, DataStax Studio will not
auto-create a graph, and the graph must be created
in the Gremlin console. In Development
mode, DataStax Studio creates a graph and aliases the graph to a graph
traversal automatically for each connection that is created.
Procedure
-
Start DSE Graph.
-
Install and start DataStax Studio.
Also create a Studio notebook, if needed.
-
In DataStax Studio, create a new connection.. Choose a
graph name; any graph previously unused will work.
-
In DataStax Studio, create a new notebook.. Select the
connection created in the last step.
A blank notebook will open with a single cell. DSE Graph runs a Gremlin
Server tinkerpop.server
on each DSE node. DataStax Studio
automatically connects to the Gremlin Server, and if it doesn't exist,
creates a graph using the connection information. The graph is stored as one
graph instance per Cassandra keyspace with a replication factor of 1 and a
strategy of SimpleStrategy
. Once a graph exists, a graph
traversal g is configured that will allow graph traversals to be
executed. Graph traversals are used to query the graph data and return
results. A graph traversal is bound to a specific traversal source which is
the standard OLTP traversal engine.
