Data missing in the parent_reference collection

Has the data been wiped out from the collection parent_reference. I am trying to do the graphLookup but coul not find any data in this collection.

Hi,

Unfortunately that collection does not exist in the aggregations database, and it’s not provided in the handouts neither. Will ask the curriculum developers to add it to the handouts.

The collection is still missing. Any updates on this one ?

Hi,

Both parent_reference and child_reference collections should be now in the aggregations database.

Yes, its there now.

Thanks a lot :slight_smile:
