Elasticsearch-重复类型

Question

我在Elasticsearch中创建了一个索引，类型为t1，文档为doc1-docN。是否有方法通过API调用创建一个新类型t2，该类型包含与t1（doc1-docN）相同的文档？

Answer 1

对此没有神奇的API调用。你需要为那些文档编制索引。我建议Elastic的一位开发人员写一篇博客文章：http://david.pilato.fr/blog/2015/05/20/reindex-elasticsearch-with-logstash/

你需要一些围绕这些线的东西：

input {
  elasticsearch {
    hosts => [ "localhost:9200" ]
    index => "test_index"
    size => 500
    scroll => "5m"
    docinfo => true
    query => '{"query":{"term":{"_type":{"value":"test_type_1"}}}}'
  }
}
filter {
  mutate {
    remove_field => [ "@timestamp", "@version" ]
  }
}
output {
  elasticsearch {
    host => "localhost"
    port => "9200"
    protocol => "http"
    index => "test_index"
    document_type => "test_type_2"
    document_id => "%{[@metadata][_id]}"
  }
}
