# BatchWriteRecord
<a name="API_feature_store_BatchWriteRecord"></a>

Writes a batch of `Records` to one or more `FeatureGroup`s. Use this API for bulk ingestion of records into the `OnlineStore` and `OfflineStore`.

You can set the ingested records to expire at a given time to live (TTL) duration after the record's event time by specifying the `TtlDuration` parameter. A request level `TtlDuration` applies to all entries that do not specify their own `TtlDuration`.
