db.mk.insertOne({"i":12, "j":17})
db.mk.createIndex({"i":1, "j":1})
on winningPlan "isMultiKey" : false.
when i insert single element array still the multikey is false
db.mk.insertOne({"i":12, "j":[17]})
on winningPlan "isMultiKey" : false.
in contrast
db.mk.insertOne({"i":[12], "j":[17,21,24,27]})
is not allowed though i is a single element array!
