NameMapping

object NameMapping extends DeltaColumnMappingMode with Product with Serializable

Name Mapping uses the physical column name as the true identifier of a column. The physical name is stored as part of StructField metadata in the schema and will be used when reading and writing Parquet files. Even if id mapping can be used for reading the physical files, name mapping is used for reading statistics and partition values in the DeltaLog.
