gateway distributes multiple systems simultaneously

[lixianli1987]

Question

The upstream system is responsible for requesting the gateway, and the gateway simultaneously pushes (in parallel) to the downstream system. The failure of a single system's reception and processing does not affect other systems.
Our idea is: a downstream system corresponds to a selector, and since the gateway is a chain of responsibility mode, it concatenates and executes various selectors. So if the previous selector (receiving system) fails to execute, it will affect the reception of other systems。
May I ask how to implement this requirement
