ABSTRACT:
A method for estimating a runtime of a query of a data repository may abstract, extract, or otherwise generate one or more parameters of the query. Thereafter, the abstracted parameters may be associated with one or more statistical query records. From these statistical query records, a query runtime may be estimated. Related apparatuses, computer program products, and computer systems are also described.
