@saimigo Are you appending the data, or overwriting? In the case of the first, you can call [`.dropDuplicates` using Spark](https://spark.apache.org/docs/3.1.2/api/python/reference/api/pyspark.sql.DataFrame.dropDuplicates.html). In the case of incremental data, you need to perform a [merge operation](https://iceberg.apache.org/docs/latest/spark-writes/#merge-into). -- This is an automated message from the Apache Git Service.
