Implication of Prometheus metric_version 2 on influxdb

So this is regarding the prometheus input plugin.

I have a setup with telegraf. where input plugin is Prometheus and output is influxline.

In the previous format (metric_version=1), the output made sense as the output format followed a pattern that was similar to the name of measurements that would be used in influxline.

But with metric_version = 2 this format seems to have changed. It seems like telegraf will output everything with the same measurement name “prometheus” (default) with what originally in version 1 was measurement name has now become a field name.

My question is now if all values go into the same measurement, how would this affect influxdb performance, as earlier what used to be measurement has now become a field

Also if I keep them as separate measurements how can I do this with the new metric_version?
