- nehanarkhede 9y agoMind clarifying what you mean by changes to events? If you create a STREAM or TABLE using KSQL, it makes sure that they are kept updated with every single event that arrives on the source Kafka topics. That's what you'd expect in a true event-at-a-time Streaming SQL engine, which is what KSQL is.
- daddykotex 9y agoSuppose you build a STREAM or TABLE from a topic and assume a field in the event is `id`. Later on, you introduce an update to this event where where your replace `id` by `user_id`, how is KSQL reacting?
