How Python Data Engineers Use Boto3

Boto3 is the essential Python library for any AWS-based data pipeline. Engineers use it to read from and write to S3, trigger Glue jobs, query Athena, publish to SNS/SQS, and manage EMR clusters — all from Python scripts or Airflow tasks. The S3 resource interface makes reading Parquet files from a data lake a few lines of code.
