  • I added CHANGELOG entry for this change.
  • Change is not relevant to the end user.

Changes

Binary expression can be vertically sharded without __name__ label if no matching labels are specified.

Image we have two series

foo{job="thanos", cluster="us"}
bar{job="thanos", cluster="eu"}

A query foo - bar is basically a join of foo and bar series. The join will ignore the metric name and will calculate hash for the rest labels in this case.

I enabled merge on green since it was approved already and fixed conflict.
Can I get another approval?
