In Snowflake, a table ' s clustering depth indicates the degree of micro-partition overlap based on the clustering keys defined for the table. A clustering depth of 1 implies that the table has no overlapping micro- partitions. This is an optimal scenario, indicating that the table ' s data is well-clustered according to the specified clustering keys. Well-clustered data can lead to more efficient query performance, as it reduces the amount of data scanned during query execution and improves the effectiveness of data pruning.

In Snowflake, when the account is located on Microsoft Azure, a valid source for an external stage can be an Azure container or a folder path within an Azure container. This includes Azure Blob storage which is accessible via the azure:// endpoint. A Windows server file share on Azure, if configured properly, can be a valid source for staging data files for Snowflake. Options A, B, and C are not supported as direct sources for an external stage in Snowflake on Azure12. References: [COF-C03] SnowPro Core Certification Exam Study Guide

In Snowflake streams, the METADATASACTION column indicates the type of data manipulation operation that has occurred. The possible values include INSERT and DELETE.
INSERT: Indicates that a new row has been inserted into the table.
DELETE: Indicates that a row has been deleted from the table.

TheGET_PRESIGNED_URLfile function in Snowflake provides a URL with access to a file on a stage without requiring authentication and authorization. This is particularly useful for sharing data files stored in Snowflake stages with external parties securely and conveniently. The presigned URL generated by this function gives temporary access to the file, which expires after a specified duration.
Example usage ofGET_PRESIGNED_URL:
SELECTGET_PRESIGNED_URL( ' < stage_name > ' , ' < file_path > ' );
This function generates a URL that can be used to directly access a file in the stage, making it easier to share data without compromising security.
