Title: Apparatus and method for streamlining index updates in a shared-nothing architecture

Abstract: An apparatus and method to streamline updates to an index in a shared-nothing architecture. The apparatus may include an association module, a consolidation module, and a processing module. The association module may associate index update requests with an index. The index update requests may be configured to update the index in response to a redistribution of data in a data table. The consolidation module may compile the index update requests prior to processing and consolidate the index update requests into a smaller number of simplified index update requests to achieve substantially the same result. The processing module may then independently process the simplified index update requests and update the index accordingly.
