2023/09/28 - Amazon SageMaker Feature Store Runtime - 3 updated api methods
Changes Online store feature groups supports Standard and InMemory tier storage types for low latency storage for real-time data retrieval. The InMemory tier supports collection types List, Set, and Vector.

{'Record': {'ValueAsStringList': ['string']}}
The PutRecord API is used to ingest a list of Records into your feature group.
If a new record’s EventTime is greater, the new record is written to both the OnlineStore and OfflineStore . Otherwise, the record is a historic record and it is written only to the OfflineStore .
You can specify the ingestion to be applied to the OnlineStore , OfflineStore , or both by using the TargetStores request parameter.
You can set the ingested record to expire at a given time to live (TTL) duration after the record’s event time, ExpiresAt = EventTime + TtlDuration , by specifying the TtlDuration parameter. A record level TtlDuration is set when specifying the TtlDuration parameter using the PutRecord API call. If the input TtlDuration is null or unspecified, TtlDuration is set to the default feature group level TtlDuration . A record level TtlDuration supersedes the group level TtlDuration .
