US Patent 10592493 Spot-instanced bulk data uploading

A database engine may maintain a collection of data on a first storage device. A workflow manager node may receive a request to bulk load data into the collection. The workflow manager may instruct a control plane node to allocate and configure a secondary database node and to make operable thereon a second database using a second storage device. Data may be bulk loaded to the second storage device using a schema and storage unit format compatible with the collection of data. Storage units from the second storage device may be transferred to the first storage device and integrated into the collection of data.
