Question

A gaming company uses Amazon Kinesis Data Streams to collect clickstream data. The company uses Amazon Data Firehose delivery streams to store the data in JSON format in Amazon S3. Data scientists at the company use Amazon Athena to query the most recent data to obtain business insights. The company wants to reduce Athena costs but does not want to recreate the data pipeline. Which solution will meet these requirements with the LEAST management effort?

Accepted Answer

Correct answer: A. The correct answer is A. Option A: Change the Firehose output format to Apache Parquet. Provide a custom S3 object YYYYMMDD prefix expression and specify a large buffer size. For the existing data, create an AWS Glue extract, transform, and load (ETL)... Amazon S3 provides durable, scalable object storage that is fully managed. Amazon Athena runs serverless SQL queries directly on data in Amazon S3 with no infrastructure to manage. AWS Glue is a serverless ETL and data-catalog service that prepares and integrates data.
