Abstract: Embodiments can provide a computer implemented method in a data processing system comprising a processor and a memory comprising instructions, which are executed by the processor to cause the processor to implement a system for providing classification job estimation for a data security platform comprising one or more data sources, the method comprising: for each of the one or more data sources: counting the number of databases; counting the number of tables in each database; selecting a random database; selecting a random table within the random database; retrieving a database data sample from the random table; measuring one or more latencies associated with issuing and retrieving the database data sample; measuring a processing time required to evaluate the database data sample against one or more policy rules; compiling one or more mean times for the latencies and processing times; and calculating a data source scan time using the one or more mean times and the number of tables in each database; and calcul

Abstract: A steam generator includes a heat exchanger, a liquid header and a steam header. The heat exchanger is assembled by several heat exchanging subassemblies with the same structure. The heat exchanging subassembly includes a spiral heat transmission pipe bundle, a central cylinder and a sleeve. The spiral heat transmission pipes with different radii are concentrically and spirally arranged in an annular space between the central cylinder and the sleeve, to form one or more concentric heat exchanging pillar surfaces. One end of the liquid header is connected with a main water feeding pipe, and the other end of the liquid header is connected with the spiral heat transmission pipe bundle. One end of the steam header is connected with a main steam pipe, and the other end of the steam header is connected with the spiral heat transmission pipe bundle.
