Abstract
An example system for processing a federated query includes a query proxy that receives a federated query including a plurality of source queries and receives an indication that a failed set of one or more source queries failed to execute successfully. Each source query is specific to an autonomous data source belonging to a federation. The system also includes a data federation engine that identifies a plurality of autonomous data sources to which to send the plurality of source queries. The plurality of autonomous data sources belong to the federation. The system further includes a query fail analyzer that updates a data structure to reflect the unsuccessful execution of one or more source queries of the failed set.
