> 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. Yea, right, current way change the schema and won't work well for all case, I am thinking about add a new class to handle nested ArrayStruct type ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
