Apache NIFi MergeContent处理器 - 将分界符设置为新行 [英] Apache NIFi MergeContent processor - set demarcator as new line

问题描述

我想使用MergeContent处理器将tweets合并到批量插入到Elasticsearch索引中。为此，我需要命令和tweets（each）由\\\
分隔。
这是它应该如
{action：{metadata}} \\\

{request body} \\\

I want to use MergeContent processor to merge tweets to bulk insert into Elasticsearch index. For this I need command and tweets (each) to be separated by \n. This is how it should look like { action: { metadata }}\n { request body }\n

哪些将是
{index）\\\

{tweet1} \\\

{tweet2} \\\

Which will be { "index" )\n { tweet1 }\n { tweet2 }\n

当我将\\\
作为分隔符时，处理器实际上将\\\
添加为字符串而不是新的行分隔符。是否可以使其成为实际的新线？
还有可能离开或使页脚空吗？

When I put \n as separator the processor actually adds \n as a string instead of new line separator. Is it possible to make it actual new line? Also is it possible to leave or make footer empty?

提前感谢。

推荐答案

你是正确的，它需要输入的字面表示。有两种方法可以解决这个问题：

You are correct in that it takes the literal representation of what is entered. There are two ways to handle this:

1. 使用文字的分隔符策略：点击Shift +输入以提供新行


2. 使用'Filename'的分隔符策略：提供只有换行符的文件的路径

关于你离开页脚的问题是空的，它应该像你预期的二进制连接的合并格式一样工作。做一个快速的测试流程，我已经验证了这一点，但是如果它不适用于您的特定配置。

With regards to your question on leaving the footer empty, it should work as you anticipate for the Merge Format of 'Binary Concatenation.' Making a quick test flow, I have verified this, but please let us know if it is not working for your particular configuration.
