Deduplicating rows
You can use the Remove duplicate rows function to easily delete all the rows that are exact duplicates and keep only one in your dataset.
Information noteNote: This
function is not compatible with Spark Jobs, and HDFS or S3 exports.
Duplicated information can be introduced in spreadsheets because of human error, like a bad copy and paste for example, as well as automated operations. In this example, you received a dataset containing customer information, where all the rows are systematically duplicated.
You will use the Remove duplicate rows to easily clean your dataset.
