questions about kylin on parquet

Hi 

I found a branch named “kylin-on-parquet” here: https://github.com/apache/kylin/tree/kylin-on-parquet. I am working on a little poc  based on it. I have a question about the function “getBatchMergeOutputSide” in class org.apache.kylin.storage.parquet.steps. ParquetMROutput(similarly ParquetSparkOutput), basically, I think there is no actually merge steps here, why is that? No need to do a merge step here?

Best Regards
