Abstract
Methods are provided of optimizing a tree-structured distributed-index with tree-nodes including data-elements and parent-child relations between tree-nodes. The distributed-index is stored in distributed system including computer-nodes each storing tree-nodes and a tree-map structurally describing the distributed-index. The methods include: inspecting the tree-map in first computer-node to determine whether the distributed-index is imbalanced due to a first tree-node in first computer-node and, in said case: notifying to other computer-nodes that first tree-node is replicable, to provoke that any request from other computer-nodes of inserting a data-element in first-tree-node includes inserting the data-element in corresponding child-node of first-tree-node; and verifying whether the other computer-nodes have been notified and, in said case, replicating data-elements stored in first tree-node into children-nodes thereof. Methods of inserting into and/or querying such distributed indexes or similar are also provided, along with computer programs and (computing) systems that are suitable for performing said optimizing, inserting and querying methods.
