A column delimiter has to be chosen that must not appear in the data itself.
必须选择不出现在数据本身中的列定界符。
Start by creating the target service; when you later create the delimiter data handler, you will understand the target service invocation specifics and will have something to test it with.
首先创建目标服务，稍后创建带分隔符数据处理程序时，您将会了解目标服务调用的具体细节，并将使用其进行一些测试工作。
If the file ends with a delimiter the (zero length) file content following the final delimiter is still propagated although it contains no data.
如果文件以分隔符结尾，则仍然传播最后一个分隔符后面的(零长度)文件内容，尽管其中没有包含数据。
