Original practice question

This is the kind of decision CramHQ checks.

Sample question Batch ingestion and transformation

An application writes 8 TB of immutable Parquet files to S3 nightly, then publishes a completion manifest at 02:00. Curated data is due by 06:00; partial or duplicate results are unacceptable. Which design is best?

  • Run one AWS Glue batch job with the STANDARD execution class after the manifest arrives; process listed objects and replace the completed date partition.Correct
  • Run a continuously active AWS Glue streaming job using Kinesis Data Streams; checkpoint incoming records and replace the date partition after the manifest arrives.
  • Start an AWS Glue batch job for every S3 Object Created event using the STANDARD execution class; compact all per-object outputs after the manifest arrives.
  • Run one AWS Glue batch job with the FLEX execution class after the manifest arrives; process listed objects and replace the completed date partition.
Why this is the answer

The manifest defines one complete input set, and consumers need only the completed result. STANDARD favors time-sensitive execution, while replacing the partition makes retries idempotent.
