Batch write and discover records in Amazon SageMaker Feature Store
aws ·
Amazon SageMaker Feature Store introduces two new APIs to address operational gaps. BatchWriteRecord allows writing up to 25 records across multiple feature groups in a single API call, offering partial-success semantics and preserving EventTime-based ordering. It also supports TTL controls at record, request, or feature-group level. ListRecords enables enumeration of record identifiers within a feature group using pagination, working with both Standard and In-Memory storage tiers. This solves the previous challenge where teams had to call PutRecord in a loop and could not discover records in the In-Memory tier if identifiers were lost. The article provides code examples and prerequisites for using the new APIs.
