Examples of asynchronous Microflow call type in a project

Can someone give me examples when he used asynchronous Microflow call type in his project instead of synchronous. What were your motivations to do so and what were the problems you encountered with default value synchronous. Thanks

Asynchronous microflow calls should be applied when the action execution time is larger than the proxy timeout. The server replies immediately after client action execution request and runs the action in background while the client polls every fifteen seconds for action completion until its done. This will prevent you from proxy timeouts, which can cause a reissue of the request (depending on the proxy configuration).
