### 物联网典型场景
在典型的物联网、车联网、运维监测场景中，往往有多种不同类型的数据采集设备，采集一个到多个不同的物理量。而同一种采集设备类型，往往又有多个具体的采集设备分布在不同的地点。大数据处理系统就是要将各种采集的数据汇总，然后进行计算和分析。对于同一类设备，其采集的数据都是很规则的。以智能电表为例，假设每个智能电表采集电流、电压、相位三个量，其采集的数据类似如下的表格：
| Device ID | Time Stamp | current | voltage | phase | location | groupId |
| :-------: | :-----------: | :-----: | :-----: | :---: | :--------------: | :-----: |
| d1001 | 1538548685000 | 10.3 | 219 | 0.31 | Beijing.Chaoyang | 2 |
| d1002 | 1538548684000 | 10.2 | 220 | 0.23 | Beijing.Chaoyang | 3 |
| d1003 | 1538548686500 | 11.5 | 221 | 0.35 | Beijing.Haidian | 3 |
| d1004 | 1538548685500 | 13.4 | 223 | 0.29 | Beijing.Haidian | 2 |
