日志聚类疑问

日志聚类中top_sen_df、top_sen_relation 只在全局初始化了一次，后续有新聚类结果写入数据库，不会被更新到top_sen_df 了，这样会影响聚类结果吧？

Start by locating the initialization and later database-write paths for top_sen_df and top_sen_relation. Trace whether newly stored clustering results are read back into these structures; done means subsequent clustering uses the current database-backed results, with relevant behavior verified by the project’s existing checks if available.
