wecharyu opened a new issue, #11635: URL: https://github.com/apache/incubator-gluten/issues/11635
### Description https://github.com/apache/incubator-gluten/pull/9026 adds `ColumnarPartialProject` when the parent is also columnar, but it should be added when the parent supports partial fallback. Here is a simple example with nested `ProjectExec`: ```sql select plus_one(col1) as col2, l_partkey from ( select plus_one(l_orderkey) as col1, l_partkey from lineitem ) ``` ```bash == Physical Plan == *(1) Project [if (isnull(col1#73L)) null else plus_one(knownnotnull(col1#73L)) AS col2#74L, l_partkey#1L] +- *(1) Project [if (isnull(l_orderkey#0L)) null else plus_one(knownnotnull(l_orderkey#0L)) AS col1#73L, l_partkey#1L] +- VeloxColumnarToRow +- ^(1) BatchScanExecTransformer parquet file:/root/workspace/gluten-community/backends-velox/target/scala-2.13/test-classes/tpch-data-parquet/lineitem[l_orderkey#0L, l_partkey#1L] ParquetScan DataFilters: [], Format: parquet, Location: InMemoryFileIndex(1 paths)[file:/root/workspace/gluten-community/backends-velox/target/scala-2.13..., PartitionFilters: [], PushedAggregation: [], PushedFilters: [], PushedGroupBy: [], ReadSchema: struct<l_orderkey:bigint,l_partkey:bigint> RuntimeFilters: [] NativeFilters: [] ``` There is a full C2R fallback even if the two `ProjectExec` supports partial projection. ### Gluten version main branch -- This is an automated message from the Apache Git Service.
