I generally believe this should be lakehouse design instead of warehouse also the database replication into data lake is classified under change data capture (cdc). If you push your data both into queue and database it’s hard to ensure consistency between the datalake and the database ie cases like rollback or database failure. Typically the state of the art solution for this type of problem is to rely on the database journal for instance through the binlog or WAL

It's indeed a lakehouse design

Thanks for sharing. But there's a thing that i do not understand, what is the point of using bus system like kafka or kinesis if the main goal is to process data in scheduled intervals? Would it to be more cost efficient to just use old school batch processing pipeline?

Sometimes yes, sometimes no. If we have the ability to process streaming data, this results in less overall data being processed and more up to date results. Sometimes this isn’t possible though, and we have to process the data in batch.

@@interviewpen I think it is more of a watered down average Joe explanations rather than higher level. Which is ok but should be reflected in the title. "Data warehousing concepts for the average Joe" would be a better title for a generic video whose audience are accountants are libertarians ... If you call it "Design a data warehouse" like you did, professionals will think that you will provide what you said you would ... Which did not materialize ...

Does consumers of Kafka also generally horizontally scale? Or are the consumers always unique (different from each other, rather than being replicas)

Yes, the consumers are stateless so scaling them just means replicating it.

I didn't learn how to design a data warehouse from this video. Misleading title. Bad.

Yep, dbt can certainly be used as an alternative to the solutions mentioned. Thanks!

Which tech is used or concept to put DB changes to the queue ? Does PG native support this? It's also scary since they can't be desynchronized

Usually we’d dump things into Kafka at the same time they’re being dumped into the database. But this is highly dependent on the system-some databases support this natively, sometimes it’s easier just to use a batch job.
