org.apache.spark.sql.execution.ProjectionOverSchema.scala. A Scala extractor that projects an expression over a given schema. I think this code also needs to have matching rules added to it. To support nested ArrayStruct. Otherwise, ParquetSchemaPruning won't work either. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
