Thanks for this article.
For me Kafka is a natural choice as the source of truth for a data lake but there are still many people that perceive this as an architectural mistake. I've gotten into several interesting discussion on this topic here https://medium.com/@RisingWave_Engineering/why-kafka-is-the-new-data-lake-dd6c1b6048e
and I've linked your article as evidence to the contrary.
The more industry examples we can spread of this architectural pattern the more we can sway the tide of thinking of Kafka as only a message queue.
