Plan Operator Specialization using Reflective Compiler Techniques
Datenbanksysteme für Business, Technologie und Web (BTW 2015)
Query-specific code generation has become a well-established approach to speed up query execution. However, this approach has two major drawbacks: (1) code generators are in general hard to write and maintain, (2) code generators lack the ability to deal with custom operators. To overcome these limitations, we suggest ...
Pack indexing for time-constrained in-memory query processing
Datenbanksysteme für Business, Technologie und Web (BTW) 2023
Main memory databases management systems are used more often and in a wide spread of application scenarios. To take significant advantage of the main memory read performance, most techniques known from traditional disk-centric database systems have to be adapted and re-designed. In the field of indexing, many ...
Energy Elasticity on Heterogeneous Hardware using Adaptive Resource Reconfiguration
Datenbanksysteme für Business, Technologie und Web (BTW 2017)
Energy awareness of database systems has emerged as a critical research topic, because energy consumption is becoming a major factor. Recent energy-related hardware developments tend towards o ering more and more configuration opportunities for the software to control its own energy-based behavior. Existing research ...
NeMeSys – Energy Adaptive Graph Pattern Matching on NUMA-based Multiprocessor Systems
NeMeSys is a NUMA-aware graph pattern processing engine, which leverages intelligent resource management for energy adaptive processing. With modern server systems incorporating an increasing amount of main memory, we can store graphs and compute analytical graph algorithms like graph pattern matching completely in-memory. ...
