ES1-索引

1.建立索引

簡單建立索引

PUT sfpay_log

建立成功

{
  "acknowledged": true,
  "shards_acknowledged": true,
  "index": "sfpay_log"
}

指定建立參數：索引分片數量、副本數量

PUT sfpay_log
{
  "settings": {
    "number_of_shards": 5, 
    "number_of_replicas": 1
  }
}

2.查看索引

索引配置信息

GET sfpay_log/_settings

查詢配置屬性

{
  "sfpay_log": {
    "settings": {
      "index": {
        "creation_date": "1530101439932",
        "number_of_shards": "5",
        "number_of_replicas": "1",
        "uuid": "IOFXzaa2SW2BWrIlz0TVlg",
        "version": {
          "created": "6020399"
        },
        "provided_name": "sfpay_log"
      }
    }
  }
}

查詢多個索引配置，索引名之間用逗號「，」連接

GET sfpay_log,sfpay_log_test/_settings

查詢結果

{
  "sfpay_log_test": {
    "settings": {
      "index": {
        "creation_date": "1530101652063",
        "number_of_shards": "5",
        "number_of_replicas": "1",
        "uuid": "aPrKgBHzSymjH_q1IxLcTQ",
        "version": {
          "created": "6020399"
        },
        "provided_name": "sfpay_log_test"
      }
    }
  },
  "sfpay_log": {
    "settings": {
      "index": {
        "creation_date": "1530101439932",
        "number_of_shards": "5",
        "number_of_replicas": "1",
        "uuid": "IOFXzaa2SW2BWrIlz0TVlg",
        "version": {
          "created": "6020399"
        },
        "provided_name": "sfpay_log"
      }
    }
  }
}

3.刪除索引

刪除sfpay_log_test

DELETE sfpay_log_test

執行結果

{
  "acknowledged": true
}

4.索引打開/關閉

關閉索引sfpay_log

POST sfpay_log/_close

關閉成功

{
  "acknowledged": true
}

關閉以後嘗試插入文檔

POST sfpay_log/waf/1
{
  "title":"屢次查詢數據"
}

返回錯誤結果：狀態爲400，索引已經關閉

{
  "error": {
    "root_cause": [
      {
        "type": "index_closed_exception",
        "reason": "closed",
        "index_uuid": "IOFXzaa2SW2BWrIlz0TVlg",
        "index": "sfpay_log"
      }
    ],
    "type": "index_closed_exception",
    "reason": "closed",
    "index_uuid": "IOFXzaa2SW2BWrIlz0TVlg",
    "index": "sfpay_log"
  },
  "status": 400
}

打開索引sfpay_log

POST sfpay_log/_open

執行結果

{
  "acknowledged": true,
  "shards_acknowledged": true
}
