Load or Unload a Property Graph Into or From the Graph Server Memory

You can load an existing SQL or PGQL property graph into the graph server memory, or unload the graph from memory.

1. Expand SQL Property Graphs or PGQL Property Graphs in the left navigation pane.

2. Expand the desired schema to view the list of property graphs to which you have access.

3. Right-click a specific graph and click Load graph into memory from the context menu.

   The confirmation slider for loading the graph into memory opens.

4. Optionally, expand Advanced Options.

   You can configure the following advanced options:

   • Ignore Invalid Edges Errors: Switch ON this toggle to ignore all edges that do not connect to a vertex.

   • Synchronizable: Switch ON this toggle to verify that the graph can be synchronized.

   • Optimized For: Select one of the following graph optimization strategies:

     • READ: Optimizes for read-intensive scenarios.

     • UPDATE: Optimizes for update-intensive scenarios.

   • Parallelism: Specify the degree of parallelism.

5. Click Load.

   The Load In Progress status next to the graph indicates that the graph loading process has been initiated. Once the graph is successfully loaded into memory, it is displayed under the Graph Server tab.

   You can then run and visualize the graph queries for the graph loaded into graph server memory.

6. Optionally, if you wish to unload the graph from memory, then right-click the graph in the Graph Server tab and select Unload graph from memory from the context menu.

   The graph is unloaded from memory.
