Abstract
Methods and a system are provided for accelerating an operation in a B+-tree. A method including forming triplets, by a triplet manager. Each of the triplets includes a pointer to a leaf node, a lower bound of a key on the leaf node, and an upper bound of the key on the leaf node. The method further includes performing, by the triplet manager, a lookup operation on the triplets responsive to the operation to avoid traversals of intermediate nodes for the operation. The method also includes executing, by a processor, the operation in the B+-tree while avoiding the traversals of the intermediate nodes for the operation responsive to a result of the lookup operation. The operation is any one of an insertion operation, a deletion operation, and a search operation.
