In my case, there are many users and every one will upload their actions to influxdb.
and the influxdb data model like
event province city sex uid
Login provinceA cityA male userA
Buy provinceA cityA male userA
PageView provinceA cityA male userA
Login provinceA cityB female userB
Logout provinceB cityC male userC
the event, province, city, sex is tag key ,and uid is field key.
The uid will be uniq, so I put it in the field key to avoid series candidate issue.
Now I want to get the users who are frequent to upload their action data. and how to realize it in influxdb or kapacitor
in this case ,The userA is the most frequent users
