测试过程

  1. 批改ilm检测周期
    indices.lifecycle.poll_interval 默认是 10min， 批改为10s
PUT _cluster/settings{  "persistent": {    "indices.lifecycle.poll_interval": "10s"  }}
  1. 创立测试策略和模版
    （1）创立策略，每写入5个文档，即触发滚动策略，滚出新的索引
PUT _ilm/policy/rollover_test_policy{  "policy": {    "phases": {      "hot": {        "min_age": "0",        "actions": {          "set_priority": {            "priority": 100          },          "rollover": {            "max_docs": 5          }        }      },      "warm": {        "min_age": "0",        "actions": {          "set_priority": {            "priority": 50          },          "forcemerge": {            "max_num_segments": 1          }        }      },      "cold": {        "min_age": "1d",        "actions": {          "set_priority": {            "priority": 0          },          "freeze": {}      }      },      "delete": {        "min_age": "1d",        "actions": {          "delete": {}        }      }    }  }}
  1. 创立模版，应用下面创立的生命周期管理策略
PUT _template/rollover_test_template{  "index_patterns": [    "rollover_test-*"  ],  "settings": {    "index.lifecycle.name": "rollover_test_policy",    "index.lifecycle.rollover_alias": "rollover_test_alias",    "number_of_replicas": 0,    "number_of_shards": 1  }}
  1. 创立初始的索引
PUT rollover_test-000001 {  "aliases": {    "rollover_test_alias":{      "is_write_index": true     }  }}

由下面信息，能够失去 rollover_test-000001处于 hot阶段的rollover步骤查看中

  1. 通过写入文档，主动触发rollover滚动
GET _alias/rollover_test_alias{  "rollover_test-000001" : {    "aliases" : {      "rollover_test_alias" : {        "is_write_index" : false      }    }  },  "rollover_test-000002" : {    "aliases" : {      "rollover_test_alias" : {        "is_write_index" : true      }    }  }}
