Graph storage in the DSE database keyspace and tables

Describes graph storage in the DSE database at a high level.

DSE Graph uses the DSE database to store schema and data. Two DSE database keyspaces are created for each graph, <graphname> and <graphname_system>. For example, for a graph called food, the two keyspaces created will be food and food_system. The first keyspace food will hold the data for the graph. The second keyspace food_system holds schema and other system data about the graph.

In the <graphname> keyspace, two tables are created for each vertex label to store vertex and edge information, vertexLabel_p and vertexLabel_e, respectively. For example, for a vertex label person, two tables are created, person_p and person_e.
