Which metric is a data point reported by system$clustering_information?

• A. total_partition_count
• B. row_count
• C. file_size
• D. query_time

Answer: (A)

system$clustering_information focuses on how data is organized for clustering, exposing metrics that reflect the table’s partitioning structure rather than its size or performance. The data point total_partition_count directly represents the number of partitions (micro-partitions) in the table, which is a core aspect of clustering information and used to assess how data is laid out for pruning and clustering efficiency. The other metrics describe row counts, storage size, or query performance, none of which specifically measure the clustering layout. Therefore, total_partition_count is the best match for what system$clustering_information reports.
