Hi, @JingsongLi, I am confused about the benefits of parquet vectorized readering. I checked spark's vector reading [slidess](https://www.databricks.com/session/vectorized-query-execution-in-apache-spark-at-facebook), and find that there are three benefits: avoid virtual function dispatch, better cache locality, avoid unnecessary copy/conversion. So what is the benefits in our flink parquet vectorized readering? BTW, is there any benchmark? -- This is an automated message from the Apache Git Service.
