How signal event can be wisely used in Microservice environment i.e say there are mutiple independent camunda +spring boot app which are working . Now if one of the Microservice raise a signal event how that can be catched in some other microservice ? Do we need to use some service bus or some kind like kafka to send some event during triggering signal event ?
Is there there any example available on the signal where service are interacting with each other ?
You can use any infrastucture to carry the signals from one microservice to the other. At the end you have to translate the message to the signal API by yourself.
