## What is the purpose of the change The performance of serializerHeavyString regresses since April 3, and had not yet recovered on April 8th. After running a series of benchmarks, I found [FLINK-34955](https://issues.apache.org/jira/browse/FLINK-34955) causes the performance regression. FLINK-34955 wants to fix CVE issues of `common-compress`, but it upgrades the `commons-io` together. I try to revert `commons-io` to 2.11.0, and the performance is recovered. ## Brief change log - [FLINK-35040] Revert `commons-io` to 2.11.0 - Revert part of `[FLINK-34955] Upgrade commons-compress to 1.26.0.
