### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) ### Search before asking - [X] I have searched in the [issues](https://github.com/apache/incubator-uniffle/issues?q=is%3Aissue) and found no similar issues. ### Describe the feature In Spark, there is a configuration, "spark.shuffle.compress", to control if we should compress shuffled data. It defaults to true. But Uniffle always compresses shuffled data without respecting the configuration. Uniffle should respect it to be more align with vanilla Spark. ### Motivation We should let user decide if compress can be applied since some workloads are not compress friendly which otherwise can avoid useless CPU cycles. ### Describe the solution We can check "spark.shuffle.compress" configuration in WriteBufferManager and RssShuffleDataIterator before compressing and decompressing. ### Additional context _No response_ ### Are you willing to submit PR? - [X] Yes I am willing to submit a PR! -- This is an automated message from the Apache Git Service.
