FileSource 新增了 dir_filter 和 extra_date_formats 参数，并修改了构造函数;并增加了 ORC/Parquet 文件表头不区分大小写的支持FileSource.headerCaseSensitive以及单文件应用的splitCount，提升了文件加载的灵活性和兼容性。 2. InputSource加入headerCaseSensitive()默认区分大小写 多文件输入功能 FileReader.java init() 只负责调用 progress(context, struct)，不再扫描文件。 文件扫描和 reader 分裂逻辑移到了 split() 方法： 调用 scanReadables() 获取所有文件 排序 创建多个 FileReader 子实例，每个对应一个文件 InputProgress.java 新版特点 - 进度管理基于 文件名 -> InputItemProgress 的 Map - 可以同时跟踪多个文件的加载状态（已加载 / 正在加载） - 支持 多线程并发 和更精细的控制（比如只确认某个文件的 offset，或者只标记某个文件 loaded） 相关接口重构 旧版 - loadingItem()：返回单个 loadingItem - addLoadingItem(InputItemProgress)：替换当前 loadingItem，旧的丢到 loadingItems - loadingOffset()：返回当前 loadingItem.offset() - markLoaded(boolean markAll)： 新版 - loadingItem(String name)：按文件名查找对应的 loadingItem - addLoadingItem(String name, InputItemProgress)：按文件名新增 - 取消了 loadingOffset()，因为已经支持多文件了，offset 必须按文件取 - markLoaded(Readable readable, boolean markAll)： - 如果传入 readable → 把对应文件从 loadingItems 移到 loadedItems - 否则（readable=null 且 markAll=true）→ 把全部 loadingItems 移过去 InputProgressDeser.java 旧版 Set loadedItems; InputItemProgress loadingItem; 用 Set 存储已完成的 items，用单对象存储正在加载的 item。 新版 Map loadedItems; Map loadingItems; 改成 Map（key 是字符串，比如文件名/ID），既能保持唯一性又能快速索引，还支持多个并发 "loading items"。 并且使用了： Collections.synchronizedMap(InsertionOrderUtil.newMap());
