Given a requirement to implement necessary logic for deduplication using Spark Structured Streaming, describe the steps you would take to ensure that duplicate records are identified and removed. Include the use of watermarking and the `dropDuplicates` method.

Simulated

Explanation:

Watermarking helps in managing the state store size by limiting the amount of state that needs to be maintained for late-arriving data. The dropDuplicates method is used to identify and remove duplicate records efficiently.
