* Purpose: The BUILD_STAGE_FILE_URL function generates a temporary, pre-signed URL that allows you to access a file within a Snowflake stage (internal or external). This URL requires authentication to use.
* Key Points:
* Security: The URL has a limited lifespan, enhancing security.
* Use Cases: Sharing staged data with external tools or applications, or downloading it directly.
* Snowflake Documentation

Snowflake's Time Travel feature is used for the maintenance of historical data, allowing users to access and restore data that has been changed or deleted within a defined period4.

Snowflake does not require source data files to be no larger than 16MB. In fact, Snowflake recommends that for optimal load performance, data files should be roughly 100-250 MB in size when compressed. However, it is not recommended to load very large files (e.g., 100 GB or larger) due to potential delays and wasted credits if errors occur. Smaller files should be aggregated to minimize processing overhead, and larger files should be split to distribute the load among compute resources in an active warehouse.

Cloud providers apply data egress charges in either of the following use cases:
Data is transferred from one region to another within the same cloud platform.
Data is transferred out of the cloud platform.
