Description
Elasticsearch-writer cleanup选项会删除Es中index的mapping, cleanup的意思应该是更加接近于sql中的`truncate`即仅删除全部的数据但是保留表结构, 这样才能保证用户特殊的属性的mapping不会因为`cleanup=true`遭到删除并且重建.

Research direction
Start with the Elasticsearch-writer cleanup option and trace how it handles the index mapping and data. Confirm that cleanup removes all data while preserving the existing mapping, then verify the behavior with the writer's available tests or a local Elasticsearch index.
