Snowflake Certification Practice Test

Can a user execute a table re-clustering to reduce micro-partition overlap and enhance performance?

1. True

2. False

3. Only under specific conditions

4. Not without admin rights

The correct answer is: False

In Snowflake, a user cannot directly execute a table re-clustering operation. While users can query data and perform various transformations, the re-clustering process is generally managed by Snowflake's automatic micro-partitioning system. Micro-partitioning is designed to optimize data storage and retrieval automatically, and Snowflake takes care of maintaining the clustering of data as needed. If a user notices performance issues related to micro-partitioning, they may need to engage with a data engineer or an administrator who has the necessary permissions to invoke re-clustering explicitly. Therefore, the assertion that a user can execute a table re-clustering to reduce micro-partition overlap and enhance performance is not accurate, leading to the conclusion that the correct answer is that a user cannot perform this action.
