This is not implemented yet but you could work on a PR that implements it

I can take this up. Is there a API design for this?
looking at how REST queries work I would assume it to look something like:

curl -X GET \
  -H "X-Parse-Application-Id: REDACTED" \
  -H "X-Parse-REST-API-Key: REDACTED" \
  -G \
  --data-urlencode 'distinct=score' \

We usually Mark custom operators with a $ i.e. $distinct

Any news regarding this enhancement ?

thanks.

[flovilmart]

@ranhsd It's up for the taking :)

[ranhsd]

@flovilmart This change should be done in the DataBaseController.js right ?

[acinader]

@ranhsd, I just poked around out of curiosity, I'd think that you'd need to add it first to RestQuery which will call find on the DataBaseController that will then use the MongoCollection.find (or postgress). Would at least need to touch a comment in LiveQuery/QueryTools.js

This is just my quick look around. Seems like following how skip and limit are done are good parallels since they are constraints on a find, like distinct is.

ymmv :)

+1 for this feature

I know MongoDB well and what would be great for me is a way to use mongo directly, with the aggregation framework and all. I know it's a lot a ask.
