- 正解だと思う選択肢: C
Parquet provides efficient columnar storage, enabling Athena to read only the necessary data for queries, which reduces scan times and speeds up query performance. Snappy compression offers a good balance between compression speed and efficiency, reducing storage costs without significantly impacting query times.
