Abstract: Methods, apparatus, systems and articles of manufacture are disclosed. An example system to aggregate partitioned data includes a plurality of nodes, queriers associated with respective ones of the plurality of nodes, and a coordinator associated with a querier, the coordinator to identify a set of nodes, decompose the a to query the database data into a plurality of sub-queries, provide the plurality of sub-queries to the queriers of the identified set of nodes for execution, store, in response to a determination that a timeout has occurred, a hinted handoff notice for a node associated with the timeout, and combine results of execution of the respective ones of the plurality of sub-queries from the queriers of the identified set of nodes not associated with the timeout to generate a response to the request to query the database data.

Abstract: Methods, apparatus, systems and articles of manufacture are disclosed. An example partitioned computer database system includes a plurality of nodes, a data director to distribute a plurality of portions of database data across the plurality of nodes, queriers associated with respective ones of the plurality of nodes, the queriers to execute respective sub-queries of respective portions of the database data, and a coordinator to receive a request to query the database data, and merge results of the plurality of sub-queries to form a response to the request.
