ES 单索引大表拆分
Johnson_wang · 2023-03-14 · via 博客园 - Johnson_wang

使用reindex 命令进行拆分,具体流程如下:

//1.查询原表,拿到表结构
GET big_data/_search
//3.调整刷新策略
PUT sm_data_1/_settings
{"refresh_interval": "1s"}


//5.同步数据
POST _reindex?wait_for_completion=false
{
  "source": {
    "index": "big_data",
    "size": 50000,
    "query": {
      "term": {
        "month": {
          "value": "202212"
        }
      }
    }
  },
  "dest": {
    "index": "sm_data_1"
  }
}

//分片同步,分片5

 POST _reindex?slices=5&refresh
 "_source": {
  "exclude": ["param"]
 }

//6.查询同步任务
GET /_tasks?detailed=true&actions=*reindex
