如何在德鲁伊查询中同时添加“和”和“或”过滤器？

如何解决如何在德鲁伊查询中同时添加“和”和“或”过滤器？

我正在尝试编写一个druid查询（json文件），该查询同时是“ and”和“ or”过滤器。我尝试过：

{
  "queryType": "select","dataSource": "timeseries_db","intervals": ["2020-09-08T17:00:00\/2020-09-08T17:30:00"],"pagingSpec":{ "threshold":100},"filter": {
    "type": "and","fields": [
      {
        "type": "selector","dimension": "orgid","value": "864e1875-ea80-455b-a835-f75bed0df2a7"
      },"filter": {
        "type": "or","fields": [
         {
           "type": "selector","dimension": "host_name","value": "testname.82fae43ca"
         },{
           "type": "selector","value": "testname.09db12d4a"
         }
        ]
      }
    ]
  },"granularity": "all"
}

我想获取组织ID为864e1875-ea80-455b-a835-f75bed0df2a7且主机名为testname.82fae43ca或testname.09db12d4a的记录

当我运行此查询时，它引发错误，提示“类型”丢失。但是我包括了“类型”。任何帮助表示赞赏。

解决方法

您不需要在"filter"过滤器内添加额外的and。试试这个：

{
  "queryType": "select","dataSource": "timeseries_db","intervals": ["2020-09-08T17:00:00\/2020-09-08T17:30:00"],"pagingSpec":{ "threshold":100},"filter": {
    "type": "and","fields": [
      {
        "type": "selector","dimension": "orgid","value": "864e1875-ea80-455b-a835-f75bed0df2a7"
      },{
        "type": "or","fields": [
         {
           "type": "selector","dimension": "host_name","value": "testname.82fae43ca"
         },{
           "type": "selector","value": "testname.09db12d4a"
         }
        ]
      }
    ]
  },"granularity": "all"
}

另一种方法是在in中使用selector过滤器，而不是两个or过滤器：

{
  "queryType": "select",{
        "type": "in","values": ["testname.82fae43ca","testname.09db12d4a"]
      }
    ]
  },"granularity": "all"
}
