Q9. In the History Page, a query shows Bytes Scanned having Assigned Partitions: 110, Scanned Partitions 58, and Original Partitions 110. Why did the optimizer show fewer partitions scanned than assigned?

Select 1 option(s):

The static optimization determined the number of possible micro partitions would be 110 but the dynamic optimization was able to prune some of the partitions from a joined table

During the execution of the query, new data was added to the table and the optimizer had to add those micro partitions into the scan.

The query was using an Xlarge warehouse and could scan the partitions in parallel

The optimizer estimated only 58 partitions would need to be scan but during the execution of the query, the optimizer realized it would have to read all 110 micro partitions

One of the tables in the query was an external table and didnt have micro partitions The metadata for the table was out of date and there were really only 58 partitions total

Snowflake utilizes per-hour billing so, customer doesn‘t have to worry about the warehouse size.

Experiment with different types of queries and different warehouse sizes to determine the combinations that best meet your specific query needs and workload.

Dont focus on warehouse size. Snowflake utilizes per-second billing, so you can run larger warehouses (Large, X-Large, 2X-Large, etc.) and simply suspend them when not in use
