However, most of this work has focused on concurrent data structures providing good worst-case guarantees, although, in real workloads, objects are often accessed at different rates. Efficient distribution-adaptive data structures, such as splay-trees, are known in the sequential case; however, they often are hard to translate efficiently to the concurrent case. We investigate distribution-adaptive concurrent data structures, and propose a new design called the splay-list. At a high level, the splay-list is similar to a standard skip-list, with the key distinction that the height of each element adapts dynamically to its access rate: popular elements “move up,” whereas rarely-accessed elements decrease in height. We show that the splay-list provides order-optimal amortized complexity bounds for a subset of operations, while being amenable to efficient concurrent implementation. Experiments show that the splay-list can leverage distribution-adaptivity for performance, and can outperform the only previously-known distribution-adaptive concurrent design in certain workloads."}],"date_updated":"2023-02-02T13:10:46Z","date_created":"2023-01-22T23:00:55Z","day":"12","article_type":"original","title":"The splay-list: A distribution-adaptive concurrent skip-list","external_id":{"arxiv":["2008.01009"]},"publication_identifier":{"eissn":["1432-0452"],"issn":["0178-2770"]},"type":"journal_article","publication":"Distributed Computing","article_processing_charge":"No","oa":1,"publisher":"Springer Nature","citation":{"chicago":"Aksenov, Vitalii, Dan-Adrian Alistarh, Alexandra Drozdova, and Amirkeivan Mohtashami. “The Splay-List: A Distribution-Adaptive Concurrent Skip-List.” <i>Distributed Computing</i>.
