Different aspects affects the efficiency of data processing. Column-oriented data storage and sparce primary index are perfecty combined with customizable compression methods, which allows to quickly access data from disk. Processing data in blocks encourages to use SIMD-optimized algorithms. Properly designed query pipeline contributes to optimal parallel data processing.
