AWS Glue is designed for ETL and this scenario.
AWS Glue offers a serverless, automated, and cost-effective solution with minimal development and operational effort, making it the best choice for this use case. Why not the other options? A. Amazon EMR cluster with Apache Spark: While EMR and Spark can handle this task, it requires more setup, maintenance, and development effort compared to AWS Glue. Managing the cluster introduces operational overhead. C. AWS Batch with Bash job definition: Using AWS Batch for this would require creating custom Bash scripts for the transformation and managing jobs. This introduces more complexity and development effort than AWS Glue D. AWS Lambda with S3 event notifications: Lambda is suitable for lightweight, real-time processing. However, converting hundreds of .csv files into Parquet format could exceed Lambda's execution time and resource limits, leading to scalability challenges.
