I'm trying to create a runtime field within an index template. I can easily divide the values of two integers like this:
emit(doc['bounce_time'].value / doc['session'].value)
bounce_time: 100 / session: 25 = 4
However I have a hash field that is essentially a uuid. Instead of dividing the
bounce_time by the
session Id like to divide the
bounce_time by the cardinality of the field
emit(doc['bounce_time'].value / doc['uuid'].value).
I'm not entirely sure how to get the cardinality of the
uuid string field before doing the division. Any help?
