The new project has now been created in the workspace. If you browse inside the project, you will see a project structure as below, with folders created for different resources such as execution-plan, publisher, receiver, and stream.

a Stream

Events are the lifeline of WSO2 CEP/DAS. They not only process data as events, but also interact with external systems using events. Event is a unit of data, and an event stream is a sequence of events of a particular type. The type of events can be defined as an event stream definition.Definitions of the event streams are stored in the file system as deployable artifacts in the  <CARBON _HOME>/repository/deployment/server/executionplanseventstreams/ directory as .siddhiqljson files. More

Stream

Follow these steps to create a new execution-planstream. Alternatively, you can import an existing execution-planstream.

  1. Open the Developer Studio Dashboard (click click Developer Studio > Open Dashboard) and click Execution-plan in click Stream in the Analytics category.
  2. Select Select Create New Execution-plan and click Stream and click Next.
  3. Type a unique name for the Execution-planStream.
  4. Do one of the following:
    • To save the
    execution-plan
    • stream in an existing Analytics project in your workspace,
    click
    • click  Browse
    and
    •   and select that project.
    • To save the
    execution-plan
    • stream in a new Analytics project,
    click
    • click Create new Project
    and
    •  and create the new project.
  5. Click Click Finish . The execution-plan stream is created in the execution-plan stream folder under the Analytics project you specified, and the execution-plan stream is open in the editor.

a Stream

Follow these steps to import an existing execution-plan stream from a .siddhiql json file into an Analytics project. Alternatively, you can create a new execution-planstream.

  1. Open the Developer Studio Dashboard (click click Developer Studio > Open Dashboard) and click Execution-plan in click Stream in the Analytics category. 
  2. Select Import Execution-plan and click Select Import Stream and click Next. 
  3. Type a unique name for the Execution-planStream. 
  4. Specify the execution-plan stream file by typing its full path name or clicking clicking Browse and  and navigating to the file. 
  5. In the Save Execution-plan Stream In field, specify an existing Analytics project in your workspace where you want to save the execution-planstream, or click click Create new Project to  to create a new Analytics project and save the execution-plan stream there. 
  6. Click Click Finish. The execution-plan stream is created in the execution-plan stream folder under the Analytics project you specified, and the execution-plan stream is open in the editor.

an Execution-plan

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 where 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 the file system as deployable artifacts in the  <CARBON _HOME>/repository/deployment/server/eventstreamsexecutionplans/ directory as .jsonsiddhiql files. More
