It is quite tedious when discussing kafka people are spouting just the contents of confluent blog posts, like you must use X serialisation, you must use X registry, when in a lot of cases you can just use protobuf.
Registry seems pretty pointless to me, and I can’t understand personally how anyone thought it was a good idea. What was the thought process? ‘oh yeah let’s write a service that our service has to query to work out how to understand the message it just received and which will crash everything if that schema service isn’t there’ - it’s microservices gone mad!
Why worry about what services talk what version of the schema when the service is guaranteed to be able to understand a message?
