SYSTEM$CLUSTERING_INFORMATION functions returns clustering information, including average clustering depth, for a table based on one or more columns in the table. The function returns a JSON object containing average_overlaps name/value pairs.
Does High average_overlaps indicates well organized Clustering?
- A . YES
- B . NO
The smaller the average depth, the better clustered the table is with regards to the specified column?
- A . TRUE
- B . FALSE
Data Engineer, ran the below clustering depth analysis function:
select system$clustering_depth(‘TPCH_CUSTOMERS’, ‘(C1, C6)’, ‘C9 = 30’); on TPCH_CUSTOMERS table, will return which of the following?
- A . An error: this function does not accept lists of columns as a third parameter.
- B . An error: this function does not accept predicates (‘C9 = 30’) as parameter.
- C . Calculate the clustering depth for a table using mentioned columns in the table.
- D . Calculate the clustering depth for a table using the clustering key defined for the table.
Mark the Correct Statements:
Statement 1. Snowflake’s zero-copy cloning feature provides a convenient way to quickly take a “snapshot” of any table, schema, or database.
Statement 2. Data Engineer can use zero-copy cloning feature for creating instant backups that do not incur any additional costs (until changes are made to the cloned object).
- A . Statement 1
- B . Statement 2
- C . Both are False.
- D . Statement 1 & 2 are correct.
Clones can be cloned, with no limitations on the number or iterations of clones that can be created (e.g. you can create a clone of a clone of a clone, and so on), which results in a n-level hierarchy of cloned objects, each with their own portion of shared and independent data storage?
- A . TRUE
- B . FALSE
