Summary
In this chapter, we learned about Delta Lake, known to be the driving force behind the modern lakehouse architecture – it truly enables the lakehouse. We learned in detail about some key features of Delta Lake, such as ACID compliance and open standards. After that, we performed common data lake table operations and showed how Delta Lake controls data isolation and concurrency levels.
In Chapter 7, Data Curation Stage – The Silver Layer, we will put the knowledge gained in this chapter to good use. Using Delta Lake, we will create the silver layer of the Electroniz lakehouse. You may recall from previous chapters that the silver layer in the lakehouse stores the curated, deduplicated, and standardized data. The silver layer represents the single source of truth of data, stored in a state that is readily consumable by diverse data analytics workloads.
