Which of the following tools is used by Auto Loader process data incrementally?
A
Checkpointing
B
Spark Structured Streaming
C
Data Explorer
Explanation:
Auto Loader uses Spark Structured Streaming to process data incrementally. Here's why:
Key Points:
Auto Loader Architecture: Auto Loader is built on top of Spark Structured Streaming, which provides the incremental processing capabilities.
How Auto Loader Works:
Checkpointing Role: While checkpointing (Option A) is used by Auto Loader to track processed files and maintain state, it's not the primary tool for incremental processing. Checkpointing is a supporting mechanism.
Data Explorer: This is a Databricks tool for exploring and visualizing data, not related to incremental data processing.
Correct Answer: B. Spark Structured Streaming - This is the underlying engine that enables Auto Loader's incremental processing capabilities.
