Description

In FileSourceStrategy, the schema of the data excluding partition columns is computed 2 times in a slightly different way:

 

val dataColumnsWithoutPartitionCols = dataColumns.filterNot(partitionSet.contains) 

vs 

val readDataColumns = dataColumns
  .filterNot(partitionColumns.contains)
