Today, AWS IoT SiteWise announced new performance enhancements that will significantly improve the retrieval of industrial data from its hot storage tier. We have improved the GetAssetPropertyValueHistory and BatchGetAssetPropertyValueHistory APIs by increasing the maximum number of results for each paginated response from 250 up to 20K. With these upgrades, developers can now retrieve asset property data, including measurements, attributes, metrics, and transforms, at high velocity to build industrial applications.
