batch-encoding 量编码
Other applications, such as video encoding, are lengthy operations that are best run "batch" style, where you start a job and leave it running while you go do something else.
其他应用程序(例如视频编码)如果是耗时非常长的操作，最好以“批处理”任务的方式运行，此时启动一个作业，让其一直运行，然后我们就可以去干别的事情了。
One feature, the chunked transfer encoding, is especially convenient in the construction of batches of messages where the size of the entire batch is not known a priori.
还有一个功能，成块传输编码，对于在预先无法知道整批大小的地方建立成批消息尤其方便。
