If i have three spring boot applications like Person, Customer, Order with spring.application.name as person, customer, order and each application has configuration in the github Person.yml, Customer.yml, Order.yml. And each application has two instances running like Person1, Person2, Customer1, Customer2, Order1, Order2 and all these are setup to read config from github and also have spring cloud bus dependencies using rabbitmq with which they all subscribe to rabbitmq broker
There is like Spring cloud config server setup to run with Spring cloud bus using rabbitmq and to read config from the above github repository.
And there is github webhook to the /monitor endpoint of the config server.
When i make configuration changes to Person.yml and save it, github will do a post to the /monitorendpoint of configserver. And config server will now post those changes to the rabbitmq broker.
At this point since all the applications are subscribing to rabbitmq would all application instances be triggered so that person1, person2, customer1, customer2, order1, order2 will all try to hit the config server and only person1 and person2 will be updated with the changes. Or only person1 and person2 applications are triggered and they hit config server since changes are only to Person.yml.
