Validation rule at object level to check if entered text is present as another field value in another object
I believe this is related to cross-object validation. Is it possible to create a validation rule on ObjA, which will validate a value of field ObjA.FieldA whether any record exists in ObjB with the same value in ObjB.FieldB?
I can't use apex code because ObjB has more than 50 million records. Currently there is no relationship between the two objects, but I can create one based on suggestions from you experts.

For future reference the validation rule on Obj A would look something like this -
ISNULL(VLOOKUP($ObjectType.ObjB.Fields.FieldB, $ObjectType.ObjB.Fields.Name, FieldA))
But ObjB should be a custom object.
