Using dedup with Neptune
I remember once i came accross AWS Neptune optimization guide that i don't remember where is it now.
It mentions that .dedup() step is not optimized for Neptune which makes performance worse.
However, I have the following scenario where i need deduplicates and pagination at same time.
So the only possible way in mind is to do .dedup() then .range()
Or
.groupCount() then select keys then range()
But i am not sure if grouping does maintain the order all the time.
What could be done?
