Explanation:

In a Snowflake Query Profile, the statistics 'Partitions scanned' and 'Bytes scanned' reflect the efficiency of query pruning. Query pruning refers to the ability of the query engine to skip unnecessary data, thereby reducing the amount of data that needs to be processed. Efficient pruning results in fewer partitions and bytes being scanned, improving query performance.
