-### Current Limitations
+### 当前限制
-Watermarking does not work very well for large backlogs of files. This is
because watermarks eagerly advance within a file, and the next file might
contain data later than the watermark.
+对于大量积压的文件， Watermark 效果不佳。这是因为 Watermark 急切地在一个文件中前进，而下一个文件可能包含比 Watermark
更晚的数据。
-For Unbounded File Sources, the enumerator currently remembers paths of all
already processed files, which is a state that can, in some cases, grow rather
large.
-There are plans to add a compressed form of tracking already processed files
in the future (for example, by keeping modification timestamps below
boundaries).
+对于无界文件源，枚举器会记住当前所有已处理文件的路径，在某些情况下，这种状态可能会变得相当大。
+计划在未来增加一种压缩的方式来跟踪已经处理的文件（例如，将修改时间戳保持在边界以下）。
