Topic #: 2
[All DAS-C01 Questions]

A large energy company is using Amazon QuickSight to build dashboards and report the historical usage data of its customers This data is hosted in Amazon Redshift The reports need access to all the fact tables' billions ot records to create aggregation in real time grouping by multiple dimensions

A data analyst created the dataset in QuickSight by using a SQL query and not SPICE Business users have noted that the response time is not fast enough to meet their needs

Which action would speed up the response time for the reports with the LEAST implementation effort?

Haha, I hear you. Spark can be a bit intimidating, but it's worth it in the long run. Although, I have to say, option D also seems like a decent choice. Stored procedures in Redshift can be pretty efficient, and we wouldn't have to worry about the complexity of Spark. Decisions, decisions...

B) Use AWS Glue to create an Apache Spark job that joins the fact table with the dimensions. Load the data into a new table

Ooh, I like that idea! Plus, with Spark, we can leverage its powerful processing capabilities to handle those billions of records. I'm definitely leaning towards option B as well. Though, I have to admit, the thought of dealing with Spark makes my head spin a little. Maybe I should have studied more during the Spark training session.

I'm not sure about that. Materialized views can be great, but they require manual maintenance and refreshes. What if the data changes frequently? I think option B, using AWS Glue to create a Spark job, might be a better approach. That way, the data is automatically updated and we don't have to worry about manual maintenance.

Hmm, this is a tricky one. We need to find a way to speed up the response time without too much implementation effort. I'm leaning towards option C - creating a materialized view in Amazon Redshift. That way, the data is already pre-joined and ready for QuickSight to use, which should improve the performance.
