> I'm a little confused on the issue this PR is addressing. Are we supporting cases like those in the below suite? https://github.com/apache/spark/blob/master/sql/catalyst/src/test/scala/org/apache/spark/sql/catalyst/expressions/SchemaPruningSuite.scala Yes, we do this to only read the fields that we need from the complex type, like `array`, `map`, `struct`, which means to prune columns for the nested columns. we enabled this feature for `HiveTableScanTransformer`, and in gluten we use it to read json/hive text, and also can be used for parquet/orc (not the default way). -- This is an automated message from the Apache Git Service.
