Does Snowflake optimize storage for semi-structured data?

Yes, based on a fixed schema
No, it does not optimize for any type of data
Yes, based on repeating elements in strings
No, it treats all data uniformly

The correct answer is: Yes, based on repeating elements in strings

Snowflake indeed optimizes storage for semi-structured data, specifically through its ability to handle repeating elements within strings efficiently. This optimization is achieved by compressing the data and allowing for more efficient querying capabilities. Snowflake's architecture allows it to store semi-structured formats such as JSON, Avro, and Parquet in a way that maintains flexibility while optimizing for performance and storage efficiency. When dealing with semi-structured data, Snowflake treats nested and hierarchical structures intelligently, providing the ability to query and analyze them without the need for a rigid, predefined schema. This flexibility is a significant advantage when working with complex data types that may contain arrays or objects. Thus, by optimizing storage based on the patterns and repetitions found within the data, Snowflake enhances both the speed and efficiency of processing semi-structured information. This capability accounts for the correct answer regarding storage optimization for semi-structured data.
