??????how about support query data by tag

[HW-Chao Wang]

Your idea is good. We can provide a query statement to find the data according 
to the tag. For example, select * from root. A.B where tag1 = 10

????:&nbsp;how about support query data by tag



Hi,


&nbsp;&nbsp;&nbsp; At present, We support using tags and attributes to add 
additional attributes to timeseries, but in fact, tags and attributes are quite 
similar to&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; influxdb's tags and fields.


&nbsp;&nbsp;&nbsp; Suppose that when I create timeseries, I add additional tags 
and attributes to uniquely identify the timeseries.


&nbsp;&nbsp;&nbsp; When querying, you can find the timeseries according to tags 
and attributes, and then query the data according to the timeseries.


&nbsp;&nbsp;&nbsp; Can we provide a syntax to query data directly according to 
tags or attributes?




Thanks!
