ES1-索引

1.建立索引

简单建立索引

PUT sfpay_log

建立成功

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

指定建立参数：索引分片数量、副本数量

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

查询配置属性

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

查询多个索引配置，索引名之间用逗号“，”连接

GET sfpay_log,sfpay_log_test/_settings

查询结果

{
  "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"

      }
    }
