Given the table SALES which has a clustering key of column CLOSED_DATE, which table function will return the average clustering depth for the SALES_REPRESENTATIVE column for the North American region?
Given the table SALES which has a clustering key of column CLOSED_DATE, which table function will return the average clustering depth for the SALES_REPRESENTATIVE column for the North American region?
The table function system$clustering_depth is used to return the average clustering depth for a specified set of columns, with an additional optional filter condition. Since the question specifies the need to calculate the average clustering depth for the sales_representative column in the North American region, this function perfectly fits the requirement.
Both A & B will give average depth. I will go with B as it only provides the average depth. https://docs.snowflake.com/en/user-guide/tables-clustering-micropartitions select system$clustering_depth('GOOGLE_ADS_DEMO.CLICK_PERFORMANCE','CAMPAIGN_ID', 'AD_GROUP_ID=''broccoli'''); The information schema will provide more information like histogram etc.
Both will work. Depth is more precise and only shows the depth. Information will show many other properties
