Fluxlang

Hello Team,

I am getting below error while i’m trying to join more than 2 measurements using Flux language.

error failed to execute query failed to initialize execute state joins currently must only have two parents

It seems it only allow to join 2 measurements, and not more than two?
This is the flux script I used.

It’s working as expected if am doing with 2 measurements. Kindly help me here.

join() currently supports joining only two input streams (note in the documentation). You can get around it by joining two streams, then using the resulting output stream in another join.

@scott Thanks, I tried multiple join and it seems working fine as expected.

Actually for InfluxDB version 2 the documentation at https://docs.influxdata.com/influxdb/v2.0/reference/flux/stdlib/built-in/transformations/join/ reads

The join() function merges two or more input streams whose values are equal on a set of common columns into a single output stream.

but it does not work yet for more than 2.
