14.12.4 Get Cached Graphs

The server state contains also cached graph information serverState.get("cached_graphs") which returns a collection of graphs cached in memory. Each entry contains information about a graph as shown:

{
   "name":"sf-1589317879394",
   "creation_timestamp":1589317879394,
   "vertex_properties":[
      {
         "loaded":true,
         "mem_size_bytes":478504,
         "name":"prop1",
         "type":"double"
      }
   ],
   "edge_properties":[
      {
         "loaded":true,
         "mem_size_bytes":1197720,
         "name":"cost",
         "type":"double"
      },
      {
         "loaded":true,
         "mem_size_bytes":598860,
         "name":"0",
         "type":"integer"
      }
   ],
   "memory":{
      "topology_bytes":3921814,
      "key_mapping_bytes":1407466,
      "property_mem_bytes":2275084
   },
   "vertices_num":59813,
   "edges_num":149715
}

The following table explains graph information fields:

Table 14-7 Graph Information

Field	Description
name	Name of the graph.
creation_timestamp	Creation timestamp of the graph.
vertex_properties	List of vertex properties, each entry contains the name, type, memory size used by the property, and a boolean flag to indicate if the property is loaded into memory.
edge_properties	List of edges properties, similar to vertex properties.
memory	Memory size used by the whole graph (topology, key mappings and properties).
vertices_num	Number of vertices.
edges_num	Number of edges.
