如何使用Bulk API将数据从一个Elasticsearch索引移动到另一个 [英] How to move data from one Elasticsearch index to another using the Bulk API

问题描述

我是Elasticsearch的新手。如何使用Bulk API将数据从一个Elasticsearch索引移动到另一个？

解决方案

我建议使用 Logstash ，即您使用一个 弹性搜索输入插件来检索索引中的数据和另一个 elasticsearch 输出插件将数据推送到其他索引。

配置logstash配置文件将如下所示：

  {
 elasticsearch {
 hosts => localhost：9200
 index => source_index< ---您的源索引名称
} 
} 
过滤器{
 mutate {
 remove_field => [@version，@timestamp] 
} 
} 
输出{
 elasticsearch {
 host => localhost
 port => 9200 
协议=> http
 manage_template => false 
 index => target_index< ----目标索引名称
 document_type => your_doc_type< ----确保设置相应的类型
 document_id => ％{id}
 workers => 5 
} 
} 
  

安装Logstash ，您可以这样运行：

  bin / logstash -f logstash.conf

解决方案

I'd suggest using Logstash for this, i.e. you use one elasticsearch input plugin to retrieve the data from your index and another elasticsearch output plugin to push the data to your other index.

The config logstash config file would look like this:

input {
  elasticsearch {
   hosts => "localhost:9200"
   index => "source_index"           <--- the name of your source index
  }
}
filter {
 mutate {
  remove_field => [ "@version", "@timestamp" ]
 }
}
output {
 elasticsearch {
   host => "localhost"
   port => 9200
   protocol => "http"
   manage_template => false
   index => "target_index"           <---- the name of your target index
   document_type => "your_doc_type"  <---- make sure to set the appropriate type
   document_id => "%{id}"
   workers => 5
 }
}

After installing Logstash, you can run it like this:

bin/logstash -f logstash.conf
