SnowPro Core Certification — Question 908

Which semi-structured file format is a compressed, efficient, columnar data representation?

Answer options

• A. Avro
• B. JSON
• C. TSV
• D. Parquet

Correct answer: D

Explanation

Parquet is the correct answer because it is specifically designed for efficient columnar storage and is optimized for both performance and compression. Avro, JSON, and TSV do not provide the same level of efficiency in columnar representation as Parquet does.
