Cache Craftiness for Fast Multicore Key
... We present Masstree, a fast key-value database designed for SMP machines. Masstree keeps all data in memory. Its main data structure is a trie-like concatenation of B+ -trees, each of which handles a fixed-length slice of a variable-length key. This structure effectively handles arbitrary-length pos ...

... Therefore, we have the following property [order(y), order(y) + size(y)] ⊂ [order(x), order(x) + size(x)] if and only if y is the child of x. When inserting a child to an existing node, it is always possible to find an interval that satisfies the property above. The computation of a new interval for ...

Abstract
... A data structure is said to be ephemeral if any changes to the structure destroy the old version. Accesses and updates can be done only on the current version. We call a data structure persistent if it supports accesses to multiple versions. The structure is partially persistent if all versions can ...

... If the tree degenerates into a long chain, then tree search becomes the same as sequential search, doing (n)comparisons on n vertices. This is the worst case for tree search. The number of vertices between the root and the target, inclusive,is the number of comparisons that must be done to find ...

The second object’s next reference can refer to a third Node object, and so on, creating a linked list of Node objects. Each node will contain some data as specified by ...

... tree in worst case time Θ(log n) (since now the height of the tree is Θ(log n) in the worst case). Insert and Delete will also take time Θ(log n) but if we use the same routine as before, they will cause violations of one of the three Red-Black properties. For instance, if we use the regular BST Ins ...
