      Guidelines:

      Should include

      • Where is a node's LogicalSessionCache informed that an operation on the session has come in (vivify)?
      • How do active sessions get refreshed? E.g. each node periodically dumps its LogicalSessionCache to config.system.sessions
      • How do expired sessions get reaped? E.g. TTL index

      Code references

      • LogicalSessionCache class
