AWS Certified Data Engineer Associate DEA-C01 Practice Question

An e-commerce company stores clickstream logs in Amazon S3 in the structure s3://logs/year=YYYY/month=MM/day=DD/. An Athena table is defined in the AWS Glue Data Catalog. New log files arrive every hour. The engineering team must make each hourly partition queryable in Athena within 5 minutes of arrival while minimizing the runtime and cost of Glue crawlers. Which solution meets these requirements?

  • Use Amazon S3 Event Notifications to invoke an AWS Lambda function that calls the Glue CreatePartition API to add the new partition when objects land.

  • Configure an AWS Glue crawler in incremental mode that is scheduled to run every 5 minutes over the entire S3 prefix.

  • Schedule an Athena MSCK REPAIR TABLE command to run every 5 minutes through an AWS Lambda function.

  • Create an AWS Glue workflow that runs a crawler over only the last 24 hours of partitions once every hour.
