Abstract: This paper introduces a lock-free linearizable search structure that supports concurrent updates, membership, and range queries accelerated by a shallow hierarchy of lightweight machine learning (ML) models. The proposed approach significantly outperforms the current state-of-the-art lock-free data structures in many workload and data distribution settings.
