ule子批次无法开始

Question

我已经使用SFTP输入创建了一个Mule批处理作业，它将无法检索csv文件。 将相同的组件移至工作流后，SFTP输入将正确轮询并检索文件。

如何获取SFTP输入以轮询并检索输入文件？

batch:input需要为Collection batch:process-records生成Collection，Iterable等，以使其在每个记录上单独起作用。 您只是传递整个文件流。

同样在上面的用例中，根本不需要批处理模块，除非您计划添加每条记录处理。

有关所有步骤的工作方式的更多信息，请参见： https : //docs.mulesoft.com/mule-user-guide/v/3.7/batch-processing
