This is a copy of https://github.com/apache/iceberg/pull/14352 Adds a `readVectored()` implementation to S3InputStream which ensures that parquet column chunks are read in parallel. ReadVectored implementations increase TPC-DS benchmark performance by ~10-20%, as without this column chunks are read sequentially leading to significant IO stalls. -- This is an automated message from the Apache Git Service.
