In an Orion HA setup, what occurs during a failover event?

• A. The API, Web UI, and data retrieval switch to a secondary node with minimal downtime.
• B. Only the database is failed over to a secondary instance.
• C. All components are restarted to re-synchronize.
• D. Failover is transparent to clients and requires no action.

Answer: (A)

Failover in an Orion HA setup is about moving the active workload from the primary node to the secondary so monitoring and access continue with minimal disruption. When failover occurs, the secondary node becomes the active one and handles the API calls, Web UI access, and data retrieval. This keeps dashboards, queries, and integrations online, with only a brief interruption as the switch happens. This is broader than just moving the database; the application services and data paths are redirected to the secondary to maintain service continuity. It also isn’t a full restart of all components—the goal is a seamless handoff with minimal downtime, not a complete reinitialization. And while the transition is automated to reduce impact, clients typically experience a short reconnection window rather than zero impact, so it isn’t entirely transparent to users.
