In a regular schema within Snowflake, the object owner has the privilege to grant object privileges. The object owner is typically the role that created the object or to whom the ownership of the object has been transferred78.

The Search Optimization Service significantly improves the performance of selective point lookup queries on tables by creating and maintaining a persistent data structure called a search access path, which allows some micro-partitions to be skipped when scanning the table

The function that provides access to download unstructured data from a Snowflake stage is:
C). GET_PRESIGNED_URL: This function generates a presigned URL for a single file within a stage. The generated URL can be used to directly access or download the file without needing to go through Snowflake.
This is particularly useful for unstructured data such as images, videos, or large text files, where direct access via a URL is needed outside of the Snowflake environment.
Example usage:
SELECTGET_PRESIGNED_URL('stage_name','file_path');
This function simplifies the process of securely sharing or accessing files stored in Snowflake stages with external systems or users.

The statistics that can be used to identify queries with inefficient pruning are 'Partitions scanned' and
'Partitions total'. These statistics indicate how much of the data was actually needed and scanned versus the total available, which can highlight inefficiencies in data pruning34.

In the Snowflake Data Marketplace, the types of data listings available include 'Vendor', which refers to the providers of data, and 'Personalized', which indicates customized data offerings tailored to specific consumer needs45.
