我下载过了，并没有什么用，没有文档没有源码。出问题也无法定位到问题。建议别用。> es动态column 有实现案例吗

您好，您改造了elasticsearchwriter 是吗？ 支持elasticsearch 7.x ? 方便提供下源码吗？

Start at the elasticsearchwriter implementation and its writer configuration, focusing on index creation, column mappings, dynamic settings, and the Elasticsearch client version. Reproduce the configuration against Elasticsearch 7.9.2; done means the writer creates the index with the requested mappings, including date formats, rather than relying on the default mapping.
