If I write the following line protocol to influxdb:
m,tag=zl v=""
The data is accepted. I can then query it out again using:
from(bucket: "devel") |> range( start: 0 ) |> filter( fn: (r) => r._measurement == "m" ) |> filter( fn: (r) => r.tag == "zl" ) |> filter( fn: (r) => r._field == "v" ) |> filter( fn: (r) => r._value == "" )
Using the command line:
influx query -r -f zero-length.flux
Which produces:
#group,false,false,true,true,false,false,true,true,true #datatype,string,long,dateTime:RFC3339,dateTime:RFC3339,dateTime:RFC3339,string,string,string,string #default,_result,,,,,,,, ,result,table,_start,_stop,_time,_value,_field,_measurement,tag ,,0,1970-01-01T00:00:00Z,2022-07-15T23:09:15.783169877Z,2022-07-15T23:07:46.992057985Z,,v,m,zl
If I try to write this back to the database using
influx write --format=csv -f zero-length.csv -b devel
I get the following error:
