Summary:A method is carried out by a data stream management system suitable for executing continuous queries on input data streams. Primary continuous queries are executed by, or provisioned to be executed by, the data stream management system on one or more input data streams in order to produce one or more output data streams. In the method, at least one secondary continuous query is generated for execution on the data stream management system on one or more input data streams. The generated secondary continuous queries are different from the primary continuous queries, and the secondary continuous queries are generated based on the at least one primary continuous query. The generation of secondary continuous queries notably enables, when ad-hoc continuous queries are requested, to quickly start outputting data streams for these ad-hoc queries. Data stream management systems and computer programs are also disclosed.
