## *Tips* - *Thank you very much for contributing to Apache Hudi.* - *Please review https://hudi.apache.org/contribute/how-to-contribute before opening a pull request.* ## What is the purpose of the pull request Fixing performance hits in reading Column Stats Index: 1. [HUDI-3834] There's substantial performance degradation in Avro 1.10 default generated `Builder` classes: they by default rely on `SpecificData.getForSchema` that load corresponding model's class using reflection, which takes a hit when executed on the hot-path (this was bringing overall runtime to read full Column Stats Index of 800k records to **60s**, whereas now it's taking mere **3s**) 2. Addressing memory churn by over-used Hadoop's `Path` creation: `Path` ctor is not a lightweight sequence and produces quite a bit of memory churn adding pressure on GC. Cleaning such avoidable allocations up to make sure there's no unnecessarily added pressure on GC. ## Brief change log See above ## Verify this pull request This pull request is already covered by existing tests, such as *(please describe tests)*. ## Committer checklist - [ ] Has a corresponding JIRA in PR title & commit - [ ] Commit message is descriptive of the change - [ ] CI is green - [ ] Necessary doc changes done or have another open PR - [ ] For large changes, please consider breaking it into sub-tasks under an umbrella JIRA. -- This is an automated message from the Apache Git Service.
