WSO2 CEP uses execution-plans to store event processing logic. An execution-plan is bound to an instance of the Siddhi complex event processing runtime, which is responsible for the actual processing of the events. The event processor allows users to configure multiple execution-plans by providing multiple isolated event processing environments per execution-plan. A typical execution-plan consists of a set of queries and related input and output event streams. Definitions of the event streams are stored in .siddhiql files as deployable artifacts in the <PRODUCT _HOME>/repository/deployment/server/executionplans directory. For more information, see Creating a Standalone Execution Plan.
