Standing query creation using store query

Abstract:

The automated creation of a dataflow graph of a standing query. Once the standing query dataflow graph is created, events may be flowed into the dataflow graph to execute the standing query. In execution, a store query is accessed. The store query is structured in accordance with a store query language. A syntax graph (such as an abstract syntax tree) of the store query may then be generated. Then, using the syntax graph and a set of rules of the store query language, the dataflow graph is automatically generated. This significant speeds up and makes more easy and efficient the conversion of a store query into a standing query.
