DeleteRecord

Deletes a Record from a FeatureGroup in the OnlineStore. Feature Store supports both SoftDelete and HardDelete. For SoftDelete (default), feature columns are set to null and the record is no longer retrievable by GetRecord or BatchGetRecord. For HardDelete, the complete Record is removed from the OnlineStore. In both cases, Feature Store appends the deleted record marker to the OfflineStore with feature values set to null, is_deleted value set to True, and EventTime set to the delete input EventTime.

Note that the EventTime specified in DeleteRecord should be set later than the EventTime of the existing record in the OnlineStore for that RecordIdentifer. If it is not, the deletion does not occur:

For SoftDelete, the existing (undeleted) record remains in the OnlineStore, though the delete record marker is still written to the OfflineStore.
HardDelete returns EventTime: 400 ValidationException to indicate that the delete operation failed. No delete record marker is written to the OfflineStore.
