数据导入与查询

导入离线数据与查询

数据导入与查询

导入离线数据与查询

• quickstart/wikipedia-2016-06-27-sampled.json文件包含了维基百科的一些日志数据（每行是一个JSON字符串）

• quickstart/wikipedia-index.json文件为离线写入任务的描述文件，其用JSON格式描述了任务的数据源、时间信息、维度信息、指标信息等

将这些数据导入到Druid中

bin/post-index-task --file quickstart/wikipedia-index.json

可能会报“ImportError: No module named argparse”的错误，执行pip install argparse安装即可解决

bin/post-index-task --file quickstart/wikipedia-index.json

查询数据

访问http://localhost:9095，可以查看当前数据集的概况和字段信息等

查询编辑次数TOP5的页面

方式一切到SQL标签，输入以下SQL

SELECT page, COUNT(*) AS Edits
FROM wikipedia
WHERE "__time" BETWEEN TIMESTAMP '2016-06-27 00:00:00' AND TIMESTAMP '2016-06-28 00:00:00'
GROUP BY page
ORDER BY Edits
DESC LIMIT 5

方式二直接通过CURL查询

quickstart/wikipedia-top-pages.json中定了查询的JSON文件

curl -X 'POST' -H 'Content-Type:application/json' -d @quickstart/wikipedia-top-pages.json http://localhost:8082/druid/v2?pretty

返回

[ {
  "timestamp" : "2016-06-27T00:00:11.080Z",
  "result" : [ {
    "count" : 29,
    "page" : "Copa América Centenario"
  }, {
    "count" : 16,
    "page" : "User:Cyde/List of candidates for speedy deletion/Subpage"
  }, {
    "count" : 16,
    "page" : "Wikipedia:Administrators' noticeboard/Incidents"
  }, {
    "count" : 15,
    "page" : "2016 Wimbledon Championships – Men's Singles"
  }, {
    "count" : 15,
    "page" : "Wikipedia:Administrator intervention against vandalism"
  } ]
} ]

实时导入与查询

发送数据

bin/generate-example-metrics可以产生一些随机的样例metric，运行下面的语句

[root@localhost imply]# bin/generate-example-metrics | curl -XPOST -H'Content-Type: application/json' --data-binary @- 
http://localhost:8200/v1/post/tutorial-tranquility-server

返回结果如下

{"result":{"received":25,"sent":25}}
