Use Graph in DataStax Studio
Graph databases are useful for discovering simple and complex relationships between objects. Relationships are fundamental to how objects interact with one another and their environment. Graph databases perfectly represent the relationships between objects.
Using DSE Graph in DataStax Studio provides an interactive way to do the following:
-
Compose Gremlin traversals and view results in multiple dynamic views such as JSON, table, charts, and graph.
-
Leverage Studio’s schema view and schema-aware content-assist for rapid Gremlin Traversal development.
-
Manipulate the graph view with interactive graph graph features that can expand vertex neighborhoods and remove vertices and edges from view.
DataStax Graph 6.8 and DataStax Studio can work with two graph engines, Core and Classic. Classic is the graph type of DSE Graph 6.7 and earlier, while Core is a new graph type for DataStax Graph 6.8. Studio can create graphs using either format. When creating a new graph in Studio, DataStax recommends using the Core graph type because Classic is included to migrate older graphs to the new Core type.

About the graph view
The Studio graph view provides a contextual view of a result by automatically populating the entire sub-graph shared between the result’s vertices and edges. The Gremlin result is examined as follows.
-
If a result contains vertices, then all edges linking those vertices are automatically populated.
-
If a result contains edges, then the adjacent vertices are automatically populated.
-
If the result is a subgraph, then it is displayed as-is.
Path results can contain arbitrary Java objects (not just vertices and edges), so path results aren’t rendered by the graph view.
Interactive graph view
Studio provides these interactive graph features:
-
Expand vertex neighborhoods, with the ability to filter by edge label
-
Remove vertices and edges from the graph view
Right-click vertices and edges to activate these features.
In a gremlin cell, you can interactively expand the neighborhood in graph view.
Edge population in neighborhood expansion happens in two stages:
-
Adjacent edges and their corresponding other vertices are retrieved.
-
Edges between new vertices and existing vertices may be automatically populated based on the selected Edge Population Strategy.
Neighborhood expansion has the following view options:
-
Populate all common edges, the default complete view.
-
Populate only the edges of the selected labels to expand.
All edges that connect a newly retrieved vertex and an existing vertex are added to the view only if their Edge Label is selected.
-
Don’t auto-populate common edges.
|
At any time, double-click the graph view to recenter the display. |
