1

Hi, Experts

as for the deletion of influxdb measurements, if i want to remove some fields from existing measurement in order to make the measurement looks simple and clean. but it seems not possible

> insert test,type="b" val=2 1504225728000123456
> select * from test
name: test
time                           caseAuthor caseName caseResult type val value
----                           ---------- -------- ---------- ---- --- -----
2017-09-01T00:28:48.000123456Z                                "b"  2

Drop series from test

I think you might need to drop a shard. Others could confirm.

thanks for your help, Yes, probably del Shard could help to remove all the information,
but not sure whether there is other way to cleanuo without Shard operation
