What is the clustering depth of a table with no micro-partitions?

• A. 0
• B. 1
• C. 2
• D. 10

Answer: (A)

Clustering depth reflects how refined the clustering is across the table’s micro-partitions. If there are no micro-partitions at all, there’s nothing to cluster, so there’s no clustering structure to measure. In that case the depth must be zero. Since the table has no micro-partitions, the clustering depth is 0.
