Based on my understanding, currently WSO2 API Management supports Gateway clustering in a Active-Passive mode. Is it possible to have API Management Gateway clustering set-up in an active-active mode whereby API requests are distributed across multiple clustering nodes simultaneously? In such a distributed scenario, we would like to ensure that API throttling quota is equally fulfilled (50% each for two nodes cluster) across multiple nodes in the cluster. Also, if a node goes down, how will the API requests quota be adjusted? Thanks.
