swapnilushinde commented on issue #24724: User friendly dataset, dataframe generation for csv datasources without explicit StructType definitions. URL: https://github.com/apache/spark/pull/24724#issuecomment-496367606 Hi, @dongjoon-hyun Thanks for reply. Yes, I use this API sometimes as well. Passing schema as DDL string is one-liner but would require to define case class for Dataset creation anyways. So, creating dataset would require to define schema as both DDL string and case class. Above change would need to define schema just once with Product class and dataset/dataframes can be created easily. Furthermore, this API is in line with all other similar APIs of creating dataset/dataframe.
