The graph server (PGX) assumes there may be multiple concurrent clients, and each client submits request to the shared PGX server independently.

Each session has its own workspace in PGX and is isolated from other sessions.

You can share graphs or properties among sessions.

The following topics describe the different session actions:

• Creating a Session
  You can create a session using the ServerInstance#createSession methods.
• Updating Session Idle Timeout
  You can configure the idle timeout value for a session.
• Destroying a Session
