However, the method
saveObject can be used for two distinct purposes: add new objects to an index or replace existing objects with an updated set of attributes.
If you intend to update your objects, you’ll need to make sure to always pass the accurate
objectID, otherwise, this would cause the creation of a new record which would increase your records usage. Total records will count towards your usage.
If you need to update your records you can also use the partialUpdateObjects method.
