背景：我们正在构建一个应用程序MuleSoft，并且作为要求的一部分，我们必须向csv文件写入大量记录（大约30K）。在此之前，我们需要以XML的形式提取数据，这些数据来自DB2的独立数据。然后我们应用一些转换/映射规则，最后我们将数据写入csv文件并FTP将csv文件。我附上XML。将大量记录写入CSV文件 - 不工作
问题：该流程仅在处理大约2500-2600条记录后才挂起。它没有抛出任何错误。它只是呆在那里，它什么都不做。我们尝试了如下的选项：1.将流程作为mule批处理流程的一部分。没有差异观察2.设置最大错误计数= -1，因为我们发现这在博客
请如果有人可以提供任何建议，这将是非常有用的。写入文件时记录数是否有限制？
