Investigate supporting arrays as label values

[juliusv]

This would be useful for things like e.g. the list of roles attached to a host and then querying only by a single role. Not sure if supporting this is worth the time and complexity though.

This would be better done as multiple timeseries each with the label value you wanted, and fits the data model generally.

I disagree. Consider a service participating in A/B testing with several experiments going on at the same time. Some requests will end up participating in more than one experiment; when reporting these separately they would be over-reported for the total request rate.

[brian-brazil]

In a case like that where timeseries aren't independent, you'd have to have a separate metric for total request rate.

This is simply not realistic to do in Prometheus anytime soon - closing.
