Abstract

Computer-implemented systems and associated operating methods implement a fast join for databases which is adapted for usage with flash storage. A system comprises a processor that performs a join of two tables stored in a storage in pages processed in a column orientation wherein column values for all rows on a page are co-located in mini-pages within the page. The processor reduces input/output operations of the join by accessing only join columns and mini-pages containing join results.
