Actual exam question for Databricks's Databricks-Certified-Data-Engineer-Associate exam
Question #: 21
Topic #: 2
Which of the following benefits is provided by the array functions from Spark SQL?

Suggested Answer: D Vote an answer

The array functions from Spark SQL are a subset of the collection functions that operate on array columns1. They provide an ability to work with complex, nested data ingested from JSON files or other sources2. For example, the explode function can be used to transform an array column into multiple rows, one for each element in the array3. The array_contains function can be used to check if a value is present in an array column4. The array_join function can be used to concatenate all elements of an array column with a delimiter. These functions can be useful for processing JSON data that may have nested arrays or objects.
