Solving the Join Ordering Problem via Mixed Integer Linear Programming
Immanuel Trummer, Christoph Koch
We transform join ordering into a mixed integer linear program (MILP). This allows to address query optimization by mature MILP solver implementations that have evolved over decade…
Probably Approximately Optimal Query Optimization
Immanuel Trummer, Christoph Koch
Evaluating query predicates on data samples is the only way to estimate their selectivity in certain scenarios. Finding a guaranteed optimal query plan is not a reasonable optimiza…
Parallelizing Query Optimization on Shared-Nothing Architectures
Immanuel Trummer, Christoph Koch
Data processing systems offer an ever increasing degree of parallelism on the levels of cores, CPUs, and processing nodes. Query optimization must exploit high degrees of paralleli…
Multiple Query Optimization on the D-Wave 2X Adiabatic Quantum Computer
Immanuel Trummer, Christoph Koch
The D-Wave adiabatic quantum annealer solves hard combinatorial optimization problems leveraging quantum physics. The newest version features over 1000 qubits and was released in A…
