Round Robin Router
Standard Support for Mule 4.1 ended on November 2, 2020, and this version of Mule will reach its End of Life on November 2, 2022, when Extended Support ends.
Deployments of new applications to CloudHub that use this version of Mule are no longer allowed. Only in-place updates to applications are permitted.
MuleSoft recommends that you upgrade to the latest version of Mule 4 that is in Standard Support so that your applications run with the latest fixes and security enhancements.
The Round Robin router iterates through a list of two or more routes in order, but it only routes to one of the routes each time it is executed. It keeps track of the previously selected route and never selects the same route consecutively. For example, the first time Round Robin executes, it selects the first route. The next time, it selects the second route. If the previously selected route is the last route in the list, Round Robin jumps to the first route.
In the example above, the first time the Round Robin is executed it prints
Route1. The next time, it prints
Route2. The third time, since there are only two routes, Round Robin starts again with the first route and prints
