in #15628/#15629 I'm adding benchmarks for variant read (plus something similar in parquet). The current numbers (see the issue) show a major performance penalty doing simple queries over shedded variants -things get about twice as slow as unshedded. That hints to me that there's reconstruction of the variant struct going on before query execution -- This is an automated message from the Apache Git Service.
