Abstract
A method includes performing a lookup using a key into a root node of a multi-tier data structure, to find a partition for performing an insert. A lookup for the key is performed on a first level index that is part of a linked data structure. A payload or reference is added to the linked data structure based on data structure criterion, otherwise the key and the payload are added to the linked data structure if the key is not found. A new first level index is created and added to the linked data structure upon the linked data structure remaining unchanged. The key and the payload or reference are added to the new index. Based on merge criterion, a new second level index is created and a portion of content from selected first level and second level indexes are merged for combining into the new second level index.
