Question 8
Which of the following statements describes Delta Lake?
Explanation:
Delta Lake is correctly described as "an open format storage layer that delivers reliability, security, and performance" (Option B). Here's why:
Delta Lake is an open-source storage layer that sits on top of data lakes and provides ACID transactions, scalable metadata handling, and unified streaming and batch data processing.
Option A is incorrect because this describes Apache Spark, not Delta Lake. Spark is the analytics engine, while Delta Lake is the storage layer.
Option C is incorrect because this describes MLflow, which is a separate platform for managing the machine learning lifecycle.
Option D is partially correct but incomplete. While Delta Lake is indeed an open-source data storage format for distributed data, the most accurate and comprehensive description is Option B, which emphasizes its role as a storage layer delivering reliability, security, and performance.
Option E is incorrect because Delta Lake doesn't process data - it stores data. Data processing is handled by engines like Apache Spark.
Delta Lake's key features include:
