我从第 3 方获取 CSV 文件。该文件的架构是动态的，我唯一可以确定的是，
- 每个包含数据的列也将具有标题名称。
- 文件将始终有一个标题。
- 标题名称将始终是一串没有空格和点的字母。（所以，有点“干净”）。
- 值应该被视为字符串，因为我不确定它们将发送什么。
现在要在我的系统中使用这种类型的数据，我正在考虑使用 MongoDB 作为暂存区。作为没有。从一个负载到另一个负载，列数、列顺序或列名不是恒定的。我认为 MongoDB 将成为一个很好的暂存区。
我读到了ConvertRecord处理器，它是 CSV 到 JSON 转换器的理想选择，但我没有架构。我只希望每一行都作为一个文档，标题名称作为键，值作为值。
我应该怎么做？此外，这个文件将在 25-30 GB 范围内，所以我不想关闭我的系统。
我想用我自己的处理器（在 Java 中）来做这件事，我能够得到我想要的东西，但它似乎花费了太多时间，而且看起来并不是最优的。
让我知道，如果这可以通过现有的处理器来实现？
谢谢，拉克什
