This is a pre-recorded lesson from V3. In this presentation, we delve into the concept of idempotent pipelines, exploring their significance, advantages, and potential drawbacks. We provide insights into Slowly Changing Dimensions (SCDs) and discuss the various types. Discover whether SCDs are inherently idempotent or not and grasp the implications of their usage in data pipelines. Join us to gain a clear understanding of these foundational concepts in data processing. [Recorded Nov 8, 2023]
