AWS Certified Data Engineer Associate DEA-C01 Practice Question

A company ingests daily JSON files into the s3://sales/raw/ prefix. An AWS Glue Spark job converts the files to Parquet and loads the results into an Amazon Redshift table. The job now takes hours because it reprocesses two years of files every night. You must limit processing to only files added since the last run without changing code. What should you do?

  • Reconfigure the job as an AWS Glue streaming job that reads from a Kinesis Data Stream.

  • Add an S3 event notification that invokes an AWS Lambda function to call StartJobRun for each new object key.

  • Enable AWS Glue job bookmarks for the existing job and keep the default run schedule.

  • Create time-based folders in Amazon S3, define an Athena external table with partition projection, and query it from Redshift Spectrum instead of using ETL.
