### 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

After overlapping compression is applied, the majority of shuffle write times is the seralization. Is it possible to replace the kyro serialization with the fast implementation like apache fory? It looks it has a impressive benchmark result .
