Managing queries performed on one or more data sources (310A, 310B, 310C) includes: storing at least a first query in a storage medium (308); selecting the first query for processing; instructing a query engine (312) to process the first query on a first portion of data in the one or more data sources for a first query interval; receiving result data (314) from the query engine based on processing the first query on the first portion of data; saving a state of the first query in the storage medium after the first query interval; instructing the query engine to process a second query during a second query interval after the first query interval; and instructing the query engine to process the first query on a second portion of data in the one or more data sources during a third query interval after the second query interval. |
