Abstract
A method may include receiving a query for data to be provided by a database server, wherein the query includes an indication of a maximum lag. The method may further include determining whether a hint is available to apply to the query, wherein the hint affects an execution of the query. When no hint is available, a baseline database server may be selected to be the database server. When the hint is available, a replication server or a cache server may be selected to be the database server based on the hint and the maximum lag. The query may be processed at the selected database server.
