wForget opened a new issue, #1586: URL: https://github.com/apache/datafusion-comet/issues/1586
### What is the problem the feature request solves? I found several possible optimizations for native scan by profiling CometReadBenchmark. 1. Snappy decompression performance is poor, `output_buf.resize` seems to account for a high proportion, is it necessary? https://github.com/apache/arrow-rs/blob/5b44d6702984fbac8a0faa93b85ec4c1120decd4/parquet/src/compression.rs#L234 2. Skip utf8 validation, see: https://github.com/apache/arrow-rs/issues/6701 ### Describe the potential solution _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
