Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for labeled caching techniques. In one aspect, a method includes placing a plurality of items into a cache, each item having a label based on metadata associated with the item. A number of accesses are performed to respective items in the cache. A per-label stack distance histogram is determined for each label, including, for each label, determining a plurality of stack distances for accesses to items having the label. The cache is adjusted using the per-label stack distance histograms. |
