Question

What are common issues found by using the Query Profile? (Choose two.)

Options

AIdentifying queries that will likely run very slowly before executing them
BLocating queries that consume a high amount of credits
CIdentifying logical issues with the queries
DIdentifying inefficient micro-partition pruning
EData spilling to a local or remote disk

Explanation

The Query Profile in Snowflake is used to identify performance issues with queries. Common issues that can be found using the Query Profile include identifying inefficient micro-partition pruning (D) and data spilling to a local or remote disk (E). Micro-partition pruning is related to the efficiency of query execution, and data spilling occurs when the memory is insufficient, causing the query to write data to disk, which can slow down the query performance.
