Hello,
Right now it is not possible, when uploading files in batch for a record dataset, to make a full sync that can remove older batches of the dataset to be fully replaced by a new batch.
The old batches can be removed from the catalog, but not from the profile when working with record datasets.
This is a problem when we work with sources that sends a full snapshot of the data, because records existing in old batches that are no longer in the recent snapshot are not deleted in AEP (think about AI models where the objective users affected by the algorithm may change)
Thanks and kind regards
