Service File: Execution Mode is Asynchronous execution
For Service File rule there are 2 Asynchronous processing options as below.
1. Execute Asynchronously (Queue For Execution)
2. Execute Asynchronously (Queue For Agent)
What is the different between them?
A request processor value has to be provided for both. The ProcessQueue agent from the Pega-IntSvcs Agents procecsses the items queued using Queue For Execution. Which agent will process Queue For Agent. Do we have to mention a custom agent for Queue For Agent? If yes, where it should be mentioned. Service Request processor does not have any field where agent name can be mentioned.
I have already referred below pdn link but it does not answer my questions above.

The agent processing queued items is the ProcessServiceQueue in the in the Pega-IntSvcs ruleset.

If the File Service execution mode is Queue for Agent the file service queues the request with status “Scheduled”, which means that it is processed by the node with the agent associated with the queue that wakes up first. This could be on any node running the agent in a multi node environment.
Instead if the execution mode is Queue for Execution the file service queues the request with status “Immediate” and spawns a batch requestor in a new thread on the same node to run the request. Thus, the queued item is processed straightaway.
This means that Queue for Agent is useful in a multi node environment to distribute the processing across the nodes.
