The architecture comes with a nice VLDB 2020 paper (which the presenter did not mention).

I see this whole "Hierarchical Data Pipeline" strategy being talked about quite a bit these days. We did establish this as part of a ready solution we built for Manufacturing use case using Confluent Kafka + KSQL. But the Data Lake is something i believe will remain/continue to exist as a depot for long term retention of data where AI/DA platforms leverage data from these data lakes for batch processing. I see this story from DataBricks to be a Data-warehouse convergence towards Data Lakes !

27.28 on automating data quality. .. isn't it same as we do quality check before we save using custom code..Will there be any additional benefits?

[@gustavemuhoza4212]

It's probably the same, but not sure how you could do that on a datalake consistently. As described here, Delta appears to make it easier to do and making it possible to do it as if you were doing it on a relational database.
