Databricks Data Engineer Associate Question 202
Select 4You are working in Databricks and need to identify the location of a user-defined function (UDF) named calculate_discount that is being used in your notebook. Which of the following approaches can help you locate the function definition?
- A
Use the search bar in the Databricks workspace to search for the function name
calculate_discount. - B
Check the imports at the beginning of the notebook to see if the function is being imported from an external library or file.
- C
Examine all cells in the current notebook to see if the function is defined locally.
- D
Inspect the Databricks Repos that the notebook is linked to, as the function might be defined in a version-controlled file.
- E
Run the
DESCRIBE FUNCTION calculate_discountcommand in a SQL cell within the notebook.
Show answer and explanation
Correct answers: A, B, C, D
Explanation
To locate the definition of a UDF like calculate_discount, you should consider all possible places where the function might reside. This includes searching the Databricks workspace, checking notebook imports, examining local notebook cells, and inspecting linked Repos. However, SQL commands such as DESCRIBE FUNCTION are only applicable to SQL functions and cannot locate Python UDFs.
- A. Correct.
The search bar in the Databricks workspace can help locate resources like notebooks, files, or functions containing the keyword, making it a valid way to locate the function.
- B. Correct.
Checking the imports is a necessary step to see if the function is being sourced from an external library or another file, which can guide you to its location.
- C. Correct.
Functions can often be defined locally within the cells of the same notebook, so examining the cells is a valid approach to identify its location.
- D. Correct.
If the notebook is linked to a Databricks Repo, the function might reside in a version-controlled file within the Repo, making it a valid place to look.
- E. Incorrect.
The
DESCRIBE FUNCTIONcommand is used for built-in or registered SQL functions, not for Python user-defined functions (UDFs), so it is not applicable in this case.
