Answer: False

The correct answer is False. While clustering keys can improve query performance by organizing data physically, they are not universally beneficial for all tables. As highlighted in the community discussion, clustering keys should be applied judiciously based on table size (e.g., very large tables >1 TB) and access patterns. Defining clustering keys on every table is unnecessary for small tables or those with specific loading orders, and it can incur maintenance overhead without performance gains. The consensus, supported by upvoted comments, confirms that this is not a best practice.
