A cloud based identity management system that handles a plurality of published events that are published and consumed by microservices provides a dynamic queue that includes one or more active queues and one or more inactive queues. Embodiments create selectors for all of the active queues and the inactive queues and binds subscribers to each active queue. Embodiments dynamically cause at least one of the inactive queues to become one of the active queues when a number of published events increases.
