    摘要： Methods, systems, and computer-readable media are disclosed for event processing with a query based on a reusable XML query template. A particular method includes receiving a plurality of events from a source and generating a plurality of event objects based on the plurality of events. A query represented by an XML file based on a reusable XML query template is executed with respect to the plurality of event objects to produce a plurality of result objects. Each result object is produced based on an application of at least one operator of the query. A plurality of results is generated based on the plurality of result objects, and the plurality of results is transmitted to a sink.

    摘要： When two or more scalar subtrees in an execution plan are directed towards the same data set, but request different data from the data set, the two subtrees are replaced in the execution plan with a new subtree which queries the data set only once. This new query to the data set covers all data required by the different subtrees. A pivoting step then is used to separate the data which would have been sought by each subtree. The pivoting step also yields data in the same form as would have resulted from the original subtrees.
