Hi all, I have a quick question regarding metrics: Is there a way of having a metric with a denominator different than the 
#success
of a binomial metric? Imagine, I want to use as a denominator the 
sum($order_value)
for those successes rather than just the count. Would that be possible of implement? Many thanks!
or for example, in the Experiment Assignment Queries, instead of just counting all the #rows, 
sum($order_values)
and use it as a denominator, in the case of $order_values being a dimension or just another entry of this assignment query?

Hi Antonio. That's not possible right now, but something we're working on soon

Thanks for the answer!
I have another question not related to the previous one, just in case you can help us with this as well: Is it possible to have two different identifiers fields (for example, 
user_id
and 
order_id
), where 
user_id
is used in the feature as splitting criterium but then we use 
order_id
as our metrics reference identifier? This is just because we are more used to calculate metrics from a transaction point of view rather than user. Many thanks again

It's possible - the ID used for bucketing/splitting in the SDK is independent of the ID used for the experiment analysis. You would need to be able to identify which order_id saw which experiment, so the trackingCallback would need to take that into account. It's a bit unusual and may cause SRM failures as the splits may not be the same.
