comphead opened a new issue, #5397: URL: https://github.com/apache/datafusion-comet/issues/5397
### What is the problem the feature request solves? Noticed dramatic slowdown for tasks with shuffle writes comparing to Spark, 2-3x to be more precise. Specifically for the nested schemas, there is some inefficiency when native shuffle deals with wide/complex fields. its invisible for TPC-* benchmarks because of historical flat schema. But in real user world this is pretty much downside. ### Describe the potential solution _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
