✨ FAQ NEW
Course: data-engineering-zoomcamp
Section: module-6 (Directly explains why repartitioning leads to multiple output files when writing parquet, fitting Spark-related questions in module-6.)
Related Issue: #237
Question
Why does Spark write multiple parquet files after repartitioning a DataFrame?
Decision Rationale
The proposal explains a Spark behavior (one output file per partition when writing) not explicitly covered by existing FAQs in module-6. It adds a clear explanation and example addressing why multiple parquet files appear after repartitioning.
