### Search before asking

- [x] I had searched in the [issues](https://github.com/apache/eventmesh/issues?q=is%3Aissue) and found no similar issues.

### Feature Request

（1）Elasticsearch 版本使用 Elasticsearch 默认 mapper
（2）需要支持 分组，排序等功能
（3）请按照 统计模块 的设计标准开发
（4）可以参考 knowstreaming

### Are you willing to submit PR?

### Code of Conduct

- [ ] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) *

Start by reading the statistics module and the project’s existing storage design, then compare the requested approach with knowstreaming. Confirm how Elasticsearch’s default mapper should be used and define the supported grouping and sorting behavior. Done means the statistics-related storage supports Elasticsearch with those capabilities.
