Increasing the Number of Concurrent Read-Only Requests of a Graph

Graph expanding increases the maximum number of concurrent read-only requests that can be processed, without changing the graph size.

• Currently, Ten-thousand-edge and Ten-billion-edge graphs cannot be expanded.
• Graphs cannot be resized after expansion. If you want to resize and expand the graph, resize the graph before you expand it.

The procedure is as follows:

1. Log in to the management console.
2. In the navigation pane, choose Graph Management. On the displayed page, locate the target graph and choose More > Expand in the Operation column.

   Only a running graph can be expanded.

3. In the displayed dialog box, set the number of nodes to be added.

4. Click OK. The graph status changes to Preparing for expansion. After a few minutes, the graph status changes to Expanding. Once the graph is successfully expanded, the graph status changes to Running.
