SnowPro Core Certification — Question 507

When unloading data, which file format preserves the data values for floating-point number columns?

Answer options

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

Correct answer: D

Explanation

Parquet is a columnar storage file format that is optimized for use with data processing frameworks and preserves the precision of floating-point numbers. In contrast, formats like CSV can lead to loss of precision due to their plain text nature, while JSON may also have similar limitations in preserving exact numeric values.
