Amazon SageMaker Feature Store now supports the ability to permanently delete records from the online store. The online store contains the most recent features and is used for low latency model serving. With this launch, you can now chose between soft delete and hard delete when deleting records, so you have more flexibility when it comes to managing online store data.

When a record is permanently deleted from the online store, Feature Store will also write a tombstone record to the offline store. The offline store contains historic features and is used for training and batch inference. Tombstone records can then be identified and removed from the offline store, for example to provide more accurate or more recent data for model training, or to reduce storage costs.
