How do you know if a table is clustered in a Snowflake?

In Snowflake, a clustered table is defined as a table that is organized based on the values in one or more columns. The primary purpose of clustering a table is to improve query performance, as it enables the data to be stored in a more efficient and easily retrievable manner.

To determine if a table is clustered in Snowflake, you can use the following command:

`SHOW TABLE <table_name>`

This command will display the table properties, including whether or not the table is clustered. If the table is clustered, the output will include the following line:

`CLUSTERING KEY ( <column_name> )`

This line specifies the column or columns that are used to cluster the table. If the table is not clustered, this line will not appear in the output.

Another way to determine if a table is clustered is to check the table properties in the Snowflake web interface. When viewing the table details, there will be a section labeled "Clustering" that will indicate whether the table is clustered or not.

In summary, to determine if a table is clustered in Snowflake, you can use the `SHOW TABLE` command or check the table properties in the web interface. If the table is clustered, the output or properties will indicate which column or columns are used for clustering.
