Hi! Is there a parameter for the conversion window similar to
'{{ startDate }}'
and
'{{ endDate }}'
? I am asking because for now, in use cases where conversion window should be infinity, the
'{{ endDate }}'
parameter gets filled by (
real end date taken from experiment configuration + conversion window
) and this leads to changing results after an experiment is stopped. Thus: 1. Having
'{{ conversionWindow }}'
parameter would allow to nicely edit metrics. 2. Also, it is not obvious that
'{{ endDate }}'
is actually experiment end date + conversion window 🙂 It gets clear after looking an rendered queries only.

Yeah, that makes sense. The original idea behind the
{{startDate}}
and
{{endDate}}
variables was for query optimization by decreasing the number of scanned rows. It was just meant as a rough filtering pass. It's clear now that it's useful for other things so we might rethink our approach a bit

Sounds good! There is a bit more I find confusing about
{{endDate}}
parameter: 1.
{{startDate}}
always corresponds to the start time of the experiment, very clear, very nice. Therefore, it is rational to assume that
{{endDate}}
corresponds to the end time of the experiment as defined in experiment configurations, but this is not the case as I understood; 2. Definition of
endDate
is different for stopped and running experiments although the parameter is the same: a. For running ones, it is `experiment end time + conversion window`; b. For stopped ones, it is
current_date + 2 days
. Can you please explain why 2 days? So, I am wondering whether it can be possible to explain this a bit better in documentation? Also, I think the name
endDate
might be misleading and maybe replacing it with
endDateAndConversionWindow
(for stopped experiments) together with
currentDatePlus2Days
(for running ones) would be more clear.
