druid如何用利用tranquityserver向druid发送实时数据。

1. 前提条件

? ?分布式druid系统安装已经完毕。

2. 下载tranquility server

官方下载地址：http://static.druid.io/tranquility/releases/tranquility-distribution-0.8.2.tgz

把 下载好的tar包解压到 /opt/tranquility-distribution-0.8.2

#cd?/opt/tranquility-distribution-0.8.2

# vi conf/server.json

内容如下：

{
  "dataSources" : {
    "mypageviews" : {
      "spec" : {
        "dataSchema" : {
          "dataSource" : "mypageviews",
          "parser" : {
            "type" : "string",
            "parseSpec" : {
              "timestampSpec" : {
                "format": "auto",
                "column": "time"
              },

              "dimensionsSpec" : {
               "dimensions": ["url", "user"]
              },

              "format" : "json"
            }
          },
          "granularitySpec" : {
            "type" : "uniform",
            "segmentGranularity" : "hour",
            "queryGranularity" : "none"
          },
          "metricsSpec" : [
                          {"name": "views", "type": "count"},
                          {"name": "latencyMs", "type": "doubleSum", "fieldName": "latencyMs"}
          ] },
        "ioConfig" : {
          "type" : "realtime"
        },
        "tuningConfig" : {
          "type" : "realtime",
          "maxRowsInMemory" : "100000",
          "intermediatePersistPeriod" : "PT1M",
          "windowPeriod" : "PT10M",
          "basePersistDirectory": "/data/persist"
        }
      },
      "properties" : {
        "task.partitions" : "1",
        "task.replicants" : "1"
      }
    }
 },
  "properties" : {
    "zookeeper.connect" : "10.70.27.8:2181,10.70.27.10:2181,10.70.27.12:2181",
    "druid.discovery.curator.path" : "/druid/discovery",
    "druid.selectors.indexing.serviceName" : "druid/overlord",
    "http.port" : "8200",
    "http.threads" : "8"
  }
}

3. 启动?tranquility

nohup bin/tranquility server -configFile conf/server.json  > ./tranquit.out 2>&1 &

4. 发送 http post 请求到transquitity server

?可以用postman来发送请求：

地址： http://10.70.27.8:8200/v1/post/mypageviews

方法： post

内容：{"time": "2018-04-02T03:15:17Z", "url": "iroot.com/overea", "user": "today2551", "latencyMs":10}

content type:?application/json

注意："time"的值得现查系统，可以在linux用下面的命令获得：

# python -c 'import datetime; print(datetime.datetime.utcnow().strftime("%Y-%m-%dT%H:%M:%SZ"))'
