There was a problem hiding this comment.
The issue that prompted this change is documented in #856 . Basically, the type UpsertBy in the tests has two unique defs. The old implementation summoned up all the uniquedefs, and this was OK since the upsert function would blow up at runtime before generating this unless the entity had exactly one unique key.
This change allows the user to provide the unique keys to upsert by. This enables backend-specific upsert-by which should be faster and safer.
