Remarks

Each RPC normalizes the partition IDs of the keys in its input entities, and always returns entities with keys with normalized partition IDs. This applies to all keys and entities, including those in values, except keys with both an empty path and an empty or unset partition ID. Normalization of input keys sets the project ID (if not already set) to the project ID from the request.
