InfluxDB：在查询结果中，为什么＆＃34;值＆＃34; key的值是否嵌套在数组中？

Question

我有一些数据存储在InfluxDB中。以下是两个查询结果：

http://influxdb.server/query?u=test&p=test&db=sensors&q=SELECT * FROM /^dwd\..*\.zehn-minuten\.niederschlag/ GROUP BY * ORDER BY DESC LIMIT 1
{"results":[{"statement_id":0,"series":[
  {"name":"dwd.str.schnarrenberg.zehn-minuten.niederschlag","columns":["time","QN","RWS_10","RWS_DAU_10","RWS_IND_10"],"values":[["2017-12-10T23:50:00Z",2,0,5,1]]},
  {"name":"dwd.str.flughafen.zehn-minuten.niederschlag","columns":["time","QN","RWS_10","RWS_DAU_10","RWS_IND_10"],"values":[["2017-12-10T23:50:00Z",2,0,0,0]]}
]}]}

两者都包含以下段

"values":[[..., ..., ...]]

将值嵌套在数组中的原因是什么？

另外，为什么结果包含在数组中？

"results":[{
