Delta Lake stores tables based on which file format?

Explanation:
Delta Lake stores the table data as Parquet files, a columnar format that enables efficient reads, compression, and predicate pushdown for analytics. The transactional information that tracks changes lives in JSON files under the _delta_log directory, with optional Parquet checkpoints for faster recovery. JSON, CSV, or ORC aren’t used to represent the actual table data in Delta Lake, so Parquet is the standard storage format.
