There is a performance related issue we're facing in Prometheus coming from
a label with a constant value across all (thousands of) time series. The
label filter in query causes a large quantity of metadata to load in memory
overwhelming Prometheus backends. Without this filter, the queries run
reasonably well. We are planning to exclude this label in ingestion in
future, but for now we need a workaround.
my_series{*global_label="constant-value"*, l1="..", l2=".."}
Is there a mechanism to automatically exclude global_label in query
configuration: remote_read subsection, or elsewhere?
thanks,
Johny
