Amazon SageMaker Feature Store introduces UpdateRecord for feature-level writes
Amazon Web Services 1 month ago 37
Amazon SageMaker Feature Store introduced the UpdateRecord API to update selected feature values in an existing feature record without performing a full read-modify-write cycle. The API limits updates to up to 100 features per call via a POST to /FeatureGroup/{FeatureGroupName}/Record. Updates are applied atomically (preserving omitted features), reducing latency, read/write costs, and preventing lost-update overwrites; it also requires Standard online stores to opt into the Standard_V2 storage format to use feature-level writes.
