if you have multiple clients that need a specific message and message retention, it is not really feasible to have each client as a consumer to Kafka and use some sort of message selector for their messages only. Think of logging tools Datadog, ELK stack, Grafana. They all index the logs and then the logs can be queried via some criteria. Kafka is a giant event log or here is Confluent's definition https://www.confluent.io/lp/apache-kafka/?utm_medium=sem&utm_source=google&utm_campaign=ch.sem_br.nonbrand_tp.prs_tgt.kafka-broad_mt.xct_rgn.namer_lng.eng_dv.all_con.kafka-general&utm_term=kafka&creative=&device=c&placement=&gad=1&gclid=CjwKCAjwivemBhBhEiwAJxNWN7pYEaj85twG5f88ExbO18-tiLHHvl-a7RGj5Cbf66LsAdAVWyjuAhoCzrAQAvD_BwE.. With offloading to Redis, we can query the events via some criteria. The main difference between Redis Streams and Reds Pubsub is that Pubsub is fire and forget. They talk about the differences here https://stackoverflow.com/questions/59540563/what-are-the-main-differences-between-redis-pub-sub-and-redis-stream

Do you have any features that need to be developed within an hour? How about 3 hours? Or do you give them days or even a sprint to code a feature(s)?

Google and Azure have decided to make Java first-class citizens Azure Spring Cloud and Spring Cloud GCP. I think this pushes Java into the future.......

Either you or I can try it with.Have you seen my article https://dzone.com/articles/running-mule-ce-embedded-in-spring-boot

If the config changes, will Mule then get the updated config changes and reconfigure flows, etc?

I am not sure I am following a point you are trying to make here in respect to the ivory tower metaphor. Are you suggesting that the leadership on architcture teams were engineers or managers? I do agree that architects in general should be applying their engineering skills to some project that is being developed within the organization. You should have a solid uderstatnding of the complete landscape from 40,000 feet as well as see it at ground level, which most developers do on a daily basis.
