Abstract: Disclosed herein are systems, methods, computing devices, and computer-readable media. For example, in some embodiments, a method for extract, transform and load (ETL) processing executed by a processing device, the method comprising: receiving, from a data catalog, field mapping between application data and a target schema; receiving from an ETL processing queue, signal comprising metadata and indicating that a record or a data file related to the application data is ready for processing; determining source data by processing the metadata to identify a location of the record or the data file and retrieving the record or the data file from the identified location; and providing source data to a table defined according to the target schema.

Abstract: A hydrogen tank having a tank structure at least partially delimiting a tank space and comprising a cooling shield formed in a lightweight construction. A conduit system, connected to the tank space, of a pressure relief system for discharging gaseous hydrogen from the tank space is formed in the cooling shield. At least one para-ortho catalyst for accelerated conversion of parahydrogen into orthohydrogen is arranged in the conduit system. A vehicle is provided having a hydrogen drive and such a hydrogen tank. A method for cooling the tank structure of such a hydrogen tank is provided.
