Thesis Topic: Query Optimization in an Environment with Non-Volatile Storage• The HANA database contains several highly optimized evaluation algorithms on columnar-stored data. The choice of the right operator implementation today is largely done based on heuristics. However, as the basis for a truly cost-based query optimizer the query evaluation time for all HANA query operators needs to be analyzed.The goal of the thesis is to develop a test harness which can be used to examine the runtime characteristics of the HANA column store. The generated measurements will be used in a regression library to derive the coefficients for the cost function formulas. The type of cost function, e.g. linear, multivariable, will be based on a code-level analysis of the operators. This cost formulas are especially vital as we aims to deploy HANA database on e.g. non-volatile memory environment instead of DRAM.Supervisor: Dr. Norman May, SAP SE (norman.may@sap.com)Advisor: Prof. Dr.-Ing Wolfgang Lehner , TU Dresden (wolfgang.lehner@tu-dresden.de)
