@KevinyhZou Thanks for your feedback. We have enabled 'GlutenParquetSchemaSuite' on Velox backend. The way we enable it is: Gluten passes user-specified schema to Velox, and the Velox reader handles the schema mismatch. For example, Gluten passes 'struct<a1>' as the output type of Velox scan node, and Velox reader handles the schema pruning internally. I wonder if CH needs this PR because the CH reader cannot handle schema pruning. Would you clarify? Thanks. > Struct<a1 string, a2 string, a3 string>, when query s.a1 from table -- This is an automated message from the Apache Git Service.
