多個索引的動態索引設定

你可以將 Index Settings 示例中顯示的相同更改應用於具有一個請求的所有現有索引，甚至是其中的一部分：

PUT /*/_settings
{
  "index": {
    "indexing.slowlog.threshold.index.warn": "1s",
    "search.slowlog.threshold": {
      "fetch.warn": "500ms",
      "query.warn": "2s"
    }
  }
}

要麼

PUT /_all/_settings
{
  "index": {
    "indexing.slowlog.threshold.index.warn": "1s",
    "search.slowlog.threshold": {
      "fetch.warn": "500ms",
      "query.warn": "2s"
    }
  }
}

要麼

PUT /_settings
{
  "index": {
    "indexing.slowlog.threshold.index.warn": "1s",
    "search.slowlog.threshold": {
      "fetch.warn": "500ms",
      "query.warn": "2s"
    }
  }
}

如果你更喜歡選擇性地執行此操作，那麼你可以選擇多個而不提供全部：

PUT /logstash-*,my_other_index,some-other-*/_settings
{
  "index": {
    "indexing.slowlog.threshold.index.warn": "1s",
    "search.slowlog.threshold": {
      "fetch.warn": "500ms",
      "query.warn": "2s"
    }
  }
}
