General FAQ

• What is a session?

  Sessions are logical data stream connections and the EMSX API supports failover betweeen physical connections. During this failover, EMSX API will handle re-subscriptions for the end application.

  If you are using multiple bloomberg API services, it is recommended to use separate sessions to avoid delaying a fast stream with slow one. For most design, it’s best to have separte session for real-time data vs. EMSX API or reference data service.

• Should I open and close sessions as needed?

  No, typically opening and closing a session is expensive for both the client’s application and for Bloomberg back-end and thus unnecessary for most application designs while using EMSX API.
