Athena Performance and Cost Control: Workgroups, Partition Projection and CTAS
Make Athena fast and safe for a whole team. You create a workgroup with an enforced result location and a per-query scan limit, define a table with partition projection, and rewrite CSV into partitioned Parquet with CTAS to cut scanned bytes.

Questions about this lab
Do I need my own AWS account?
No. When you start the lab, Cloud Arena gives you a real, temporary AWS account with its own login, locked to one region. You work in the real AWS Management Console, not a simulator.
Will AWS charge me anything?
No. Cloud Arena pays for the AWS resources, and everything you create is deleted automatically when you stop the lab or the session ends. Nothing is billed to you by AWS.
How long does the Athena Performance and Cost Control: Workgroups, Partition Projection and CTAS lab take?
Plan for about 45 minutes. The session timer is shown on screen, and every task is checked against your live AWS account when you click Verify.
How do I get access to this lab?
It is included in the AWS Certified Data Engineer – Associate plan: a one-time payment for every lab in the path, 2 attempts per lab and a 7-day money-back guarantee. You can also start with the 5 free labs.
Does this lab help with the Data Engineer – Associate (DEA-C01) exam?
Yes. It is part of the AWS Certified Data Engineer – Associate path, which covers the hands-on skills behind the exam. Doing the task in a real account is what makes the questions easier to reason about.
