WebB-trees [Bayer and McCreight 1972] are primary data structures not only in databases but also in information retrieval, file systems, key-value stores, and many application-specific indexes. Compared to the simpler binary trees, B-trees are more suitable to paged environments such as virtual memory, traditional disk storage, flash devices, Webmechanisms such as hierarchical locking. Our proposal is less complicated and does not involve hierarchies. We group elements together, such that only one lock per group must be acquired. 2. RELATED WORK For database systems, predicate locks are an approach to logically lock elements [1]. A predicate, such as \all data
