AWS IoT SiteWise now allows ingestion of data that is up to 7 days old
AWS IoT SiteWise now supports ingestion of data that is up to 7 days old (extended from 15 mins). Late data may be ingested in to AWS IoT SiteWise using the AWS IoT SiteWise connector (which runs on your edge devices), AWS IoT Core or the BatchPutAssetPropertyValue API directly. This would enable you to transmit any accumulated data to AWS IoT SiteWise when recovering from intermittent connectivity issues. To get the most out of this feature, please upgrade to version 8 (latest) of IoT SiteWise connector that runs on AWS IoT Greengrass. AWS IoT SiteWise automatically calculates (or recalculates) related transforms or metrics on arrival of late data. To learn more, visit the late data ingestion page in the AWS IoT SiteWise user guide.
