Question
A data engineer needs to schedule a workflow that runs a set of AWS Glue jobs every day. The data engineer does not require the Glue jobs to run or finish at a specific time.
Which solution will run the Glue jobs in the MOST cost-effective way?
- A. Choose the FLEX execution class in the Glue job properties. Correct
- B. Use the Spot Instance type in Glue job properties.
- C. Choose the STANDARD execution class in the Glue job properties.
- D. Choose the latest version in the GlueVersion field in the Glue job properties.
Explanation
The correct answer is A because choosing the FLEX execution class for AWS Glue jobs allows them to run using spare capacity within AWS, which can significantly reduce costs compared to the STANDARD execution class. This option is ideal when the exact start or completion time of the job is not critical.
