Of these benchmarks, TPC-C, TPC-H, and TPC-E, TPC-DS, TPC-DI, TPC-V and the new TPCx-HS are currently active. TPC Pricing Specification and TPC Energy Specification are common across all benchmark standards designed to allow a fair comparison for pricing and energy efficiency. To address the increased benchmark development cycle and development costs, in 2103, the TPC created new benchmark development track called the “express benchmark”, easy to implement, run and publish, and less expensive and available online via downloadable kit.

On the other hand, a distributed file system such as HDFS might be sufficient to store messages containing information from office building room temperature sensors. g. a NoSQL system) is also typically required to manage information about the edge and gateway devices. Such information typically includes the ID and owner of the device, location, model number and other details, software patch version etc. Occasionally, it is necessary to send updates or new information to the devices, for example, to deliver software upgrades, or change configuration settings.

We never did an in depth statistical analysis, but looking at the results of run times and records processed of individual queries in detail it’s obvious that for each navigation step only a limited number of variations of an individual step seemed to be possible. 5 Results of the Benchmarks So far the following 9 results have been published for the SAP BW-EML standard application benchmark Fig. 3. 9,10 The result of a series of identical performance test runs using the BW-EML workload was that the variability between the different runs is less than 1 %.
