Explanation:
The MERGE command in Databricks is used to merge a source DataFrame into a target Delta table. It allows you to insert new records and update or delete existing ones based on a condition. This helps in avoiding the writing of duplicate records by ensuring that only new or modified records are inserted or updated, respectively.
