<p>The columns to cluster. Clusters are an alternative to partitions. They can help optimize performance for some database queries, such as read operations on some table filters. Databricks recommends using clustering for all new tables you create.

<p class="tip" MadCap:autonum="&lt;b&gt;Tip: &lt;/b&gt;">Databricks does not allow you to drop tables containing clustered columns.
