Snowflake SnowPro Certification Practice Test

Which of the following compression methods is NOT supported when unloading data in Snowflake?

1. Gzip

2. Brotoli

3. Bzip2

4. Zip

The correct answer is: Zip

When unloading data in Snowflake, the method that is not supported is Zip. Snowflake provides various compression options to optimize data storage and processing efficiency. Gzip, Brotli, and Bzip2 are all recognized as valid compression formats that can be utilized when exporting or unloading data from Snowflake. Gzip is commonly used because it provides a good balance between compression ratio and speed. Brotli offers even better compression ratios, particularly for text data, making it an attractive option for web-related data exports. Bzip2, while slower than Gzip, provides a higher compression ratio, which can be beneficial for large datasets. However, Zip is not among the supported methods for data unloading in Snowflake. This limitation exists because Snowflake has optimized its architecture and the supported formats to ensure performance efficiency and compatibility with its overall data handling processes. Thus, knowing the supported formats is critical for effective data management within the Snowflake environment.
