Learn about what happens when agents register and then heartbeat to Edge Flow Manager.

Prewarming Edge Flow Manager

When a new agent class is created with agents having a manifest unknown to the Edge Flow Manager, it is highly recommended to register only a small number of agents before letting the traffic of the total agents on the Edge Flow Manager.

The reason behind this is when a new manifest is registered in the Edge Flow Manager, it involves a heavy database operation. When many agents (for example, hundreds) concurrently try to register the same manifest, it leads to a race condition, which can cause the Edge Flow Manager to hang and refuse serving requests.
