## Evidence

Verbatim from https://aws.amazon.com/blogs/machine-learning/batch-write-and-discover-records-in-amazon-sagemaker-feature-store/:

> Today, we are announcing two new APIs for Amazon SageMaker Feature Store: BatchWriteRecord — Write up to 25 records across multiple feature groups in a single API call, with partial-success semantics, per-record time-to-live (TTL) control, and the same EventTime-based ordering guarantees as PutRecord. ListRecords — Enumerate record identifiers within a feature group using pagination. Works with both Standard ( Amazon DynamoDB -backed) and In-Memory ( Redis -backed) storage tiers.
