Abstract
The presently disclosed subject matter includes a system and method of managing computer memory of a column-oriented database, which enables to reduce the tradeoff between eviction and recycling of intermediate query results and thus retain much of the recycling capability at a considerably lower computer memory cost. The computer memory comprises one or more intermediates, each intermediate being generated by execution of a respective instruction, the instruction being part of a given query. An hierarchical data-structure is generated and stored in the computer memory, wherein different nodes in the hierarchical data-structure represent different respective intermediates stored in the computer memory. Responsive to a delete command, the at least one intermediate is deleted from the computer memory, while a respective node representing the at least one intermediate is maintained in the hierarchical data-structure.
