SageMaker Feature Store Adds BatchWriteRecord for 25 Records Across Feature Groups in One Call

AWS shipped two APIs to Amazon SageMaker Feature Store: BatchWriteRecord writes up to 25 records spanning multiple feature groups in a single call, and ListRecords enumerates record identifiers within a feature group. The batch write is the practical one, collapsing per-record round trips in ingestion pipelines; ListRecords fills a longstanding gap where you could not enumerate what was actually stored without an external index. Straightforward plumbing, but it removes two workarounds most teams had built by hand.
