Snowflake SnowPro Certification Practice Test

Which file format is NOT supported by Snowflake for data loading?

1. ORC

2. HTML

3. JSON

4. Parquet

The correct answer is: HTML

Snowflake supports various file formats for data loading to provide flexibility and cater to different data storage needs. The formats that are supported include ORC, JSON, and Parquet, which are widely used in analytics and big data environments for their efficiency and performance in handling semi-structured and structured data. ORC (Optimized Row Columnar) and Parquet are both columnar formats that are optimized for query performance and can efficiently store large datasets, making them suitable for analytical purposes. JSON (JavaScript Object Notation) is a popular format for representing data structures, especially when dealing with semi-structured data, and is well-supported by Snowflake for data ingestion. HTML (HyperText Markup Language), on the other hand, is primarily a markup language for creating web pages and is not designed for data loading purposes in the same way the other formats are. Snowflake does not support HTML as a file format for data loading, as it lacks the structured approach necessary for effective data ingestion and processing. Therefore, the identification of HTML as the unsupported file format is accurate, as it does not fit within Snowflake's capabilities for data processing.
