Part 7/11:
Several cloud providers (Amazon, Google, Microsoft) have introduced "zero-ETL" or ELT architectures that emphasize loading raw data into data lakes or cloud storage and transforming it as needed downstream, often in a more flexible, on-demand fashion.
While the idea of completely removing extract and load steps is promising, the speaker cautions that the reality is nuanced: achieving a fully zero-ETL environment, especially for transactional data with high integrity requirements, remains a challenge. Building such systems requires new capabilities and architectures that address issues like data quality, ownership, governance, and lineage.
