Abstract

A method for reclaiming memory resources may include segmenting a plurality of memory resources in an in-memory database into a first resource partition and a second resource partition; generating, for the first resource partition, a first heap containing a first plurality of memory resources sorted based on an age of data occupying the first plurality of memory resources; generating, for the second resource partition, a second heap containing a second plurality of memory resources sorted based on an age of data occupying the second plurality of memory resources; and when a shortage of memory resources is detected, identifying, from the first heap, a first memory resource containing a least recently used data, identifying, from the second heap, a second memory resource containing a least recently used data, and reclaiming the first memory resource and/or the second memory resource. Related systems and articles of manufacture are also disclosed.
