💡 Model Answer
Yes. A DynamicFrame is an AWS Glue abstraction built on top of Apache Spark's DataFrame. It adds schema inference, support for semi‑structured data (JSON, Parquet, CSV), and built‑in transformations (selectFields, applyMapping, resolveChoice). Under the hood, a DynamicFrame is backed by a Spark DataFrame, so you can convert it with toDF() and use all Spark APIs. This makes it possible to run Glue ETL jobs on Spark clusters while still leveraging Glue's catalog and job orchestration.
