The Parquet Row Iterator step allows for batch processing on Parquet files. Like a Subflow, it requires another Flow that will perform the desired actions. This Step is similar to the Run Flow for List Step. Note that this step will only work for Parquet files.
This article describes all the Step Properties to use to iterate rows of a Parquet File.
