宁静不向德鲁伊发送数据

Question

我正在为我的用例评估 Druid，它通过 tranquility 实时摄取 csv 数据。以下是服务器配置：-

{
  "dataSources" : {
    "audience" : {
      "spec" : {
        "dataSchema" : {
          "dataSource" : "audience",
          "parser" : {
            "type" : "string",
          "parseSpec":{
    "format" : "csv",
    "timestampSpec" : {
      "column" : "timestamp"
    },
    "columns" : ["timestamp","partner_id","event_id","product_id","device_id","count"],
    "dimensionsSpec" : {
      "dimensions" : ["partner_id","event_id","product_id","device_id"]
    }
  }
},
          "metricsSpec" : [{ "type" : "longSum", "name" : total, "fieldName" : "count" }],
  "granularitySpec" : {
    "segmentGranularity" : "HOUR",
    "queryGranularity" : "HOUR",
    "intervals" : [ "2013-08-31/2013-09-01" ]
  }

  },
        "ioConfig" : {
          "type" : "realtime"
        },
        "tuningConfig" : {
          "type" : "realtime",
          "maxRowsInMemory" : "100000",
          "intermediatePersistPeriod" : "PT10M",
          "windowPeriod" : "PT10M"
        }
      },
      "properties" : {
        "task.partitions" : "1",
        "task.replicants" : "1"
      }
    }
  },
  "properties" : {
    "zookeeper.connect" : "localhost",
    "druid.discovery.curator.path" : "/druid/discovery",
    "druid.selectors.indexing.serviceName" : "druid/overlord",
    "http.port" : "8200",
    "http.threads" : "8"
  }
}

数据由 python 脚本随机生成为：-

1471336991,1,960,136,3ZLA7,1
1471336991,1,369,367,8MP2B,1
1471336991,2,544,550,C9ZG8,1
1471336991,1,135,394,XFX31,1
1471336991,2,590,552,VXMTL,1
1471336991,1,493,615,0C2HR,1
1471336991,2,435,710,HKYP0,1
1471336991,1,394,483,V2HP9,1
1471336991,2,441,376,J1LYO,1

以下命令提交数据和returns {"result":{"received":1000,"sent":0}}

python createData.py |curl -XPOST -H'Content-Type: text/plain' --data-binary @- http://localhost:8200/v1/post/audience.

Answer 1

终于可以解决问题了。实际上我是以 Epoch 时间格式向 Druid 发送时间，但它期望 ISO-8601 格式。在 python 中，可以通过以下方式轻松获得：-

datetime.datetime.utcnow().isoformat()

Answer 2

Druid 支持多种时间格式，可以在"timestampSpec" 属性中指定。 Druid 文档列出了以下时间戳格式："iso, millis, posix, auto or any Joda time format."

例如以毫秒为单位发送时间：

"timestampSpec" : {
    "column" : "timestamp",
    "format" : "millis"
 }

Answer 3

几件事

使用 ISO 8601 日期时间格式
确保写入的时间戳在当前小时的 +/- 10 分钟内
