How many cluster keys can reside on a Snowflake table?

The correct answer is: 1

In Snowflake, a table can have only one cluster key defined at a time. The cluster key is used to determine how the data is organized within the micro-partitions in Snowflake. By specifying a single cluster key, users can optimize their query performance by sorting and organizing data in a way that can be more efficient for specific types of queries. Having multiple cluster keys is not supported because it would introduce complexity and ambiguity in how data is physically stored and accessed. By limiting it to one cluster key, Snowflake ensures that there is a clear and straightforward method to optimize the storage and retrieval of data, making it easier for users to manage their datasets effectively.
