SageMaker Feature Store adds batch writes and record discovery

AWS announced BatchWriteRecord and ListRecords APIs for Amazon SageMaker Feature Store. BatchWriteRecord accepts up to 25 records across feature groups in one request while retaining EventTime ordering and returning individual failures for retry. ListRecords paginates active record identifiers in both Standard and In-Memory tiers, allowing customers to find records previously unavailable for enumeration. AWS says the change supports bulk ingestion and data-deletion workflows, although ListRecords returns identifiers rather than feature values and concurrent writes can produce duplicates or gaps.
