弹性搜索 - 重新索引到相同的索引名称 [英] Elasticsearch--reindexing to the same index name

问题描述

我有几个旧的索引，我想改变映射。现在我需要将旧映射转化为新映射。我一直在阅读stackoverflow，如

这一个

这一个

和这一个

但我不认为他们是我的确切答案问题。

许多使用不同的索引名称，因此操作更容易，但由于安装，我们使用更粗略的方法来卷曲数据，这需要确切的索引名称。

现在我的问题是：将旧索引（或几个索引）重新索引到新的索引是一个好方法

ex。

我的当前地址将是 http：// address-to-server：port / cluster-name / index-name '

我想要重建索引旧数据使得当我 curl -XGET'http：// address-to-server：port / cluster-name / index-name'它会给旧

解决方案

作为我的以前的答案，您可以使用重建索引插件来执行映射更改操作

还要确保您的新映射有效，并通过检查样本输入数据

将采用您的旧数据

I have several old indices which I'd like to change mapping of. Now I need to transform old mapping into new ones. I've been reading on stackoverflow like

This one

This one

and this one

But I don't think they're the exact answer to my question.

Many of those use a different index name, so operation is easier that way, but due to the setup, we use a more crude way of curl-ing the data, which requires the exact index name.

Now my question is: what's a good way to reindex an old index (or several indices) to new one

ex.

my current address would be 'http://address-to-server:port/cluster-name/index-name'

I want to be able to reindex the old data so that when i curl -XGET 'http://address-to-server:port/cluster-name/index-name' it'll give the the old data in new mapping (some additional fields, some modified)

解决方案

As my previous answer you can use reindexing plugins to perform the mapping change actions

And also make sure that your new mapping is valid and will adopt your old data by checking sample input data
