Authoring Methods

SAP Event Stream Processor Studio provides visual and text authoring environments for developing projects.

In the visual authoring environment, you can develop projects using graphical tools to define streams and windows, connect them, integrate with input and output adapters, and create a project consisting of queries.

In the text authoring environment, you can develop projects in the Continuous Computation Language (CCL), as you would in any text editor. Create data streams and windows, develop queries, and organize them in hierarchical modules and projects.

You can easily switch between the Visual editor and the CCL editor at any time. Changes made in one editor are reflected in the other.

In addition to its visual and text authoring components, the Studio includes environments for working with sample projects, and for running and testing applications with a variety of debugging tools. You can record and playback project activity, upload data from files, manually create input records, and run ad hoc queries against the server.

You can compile projects into an executable project file. The project file can be shared, tested, developed, and run in the Studio regardless of the operating system on which it was compiled.

You can access all ESP Studio components and features from within SAP HANA studio, as well as some SAP HANA-specific features, using the SAP Event Stream Processor plugin for SAP HANA studio.

If you prefer to work from the command line, you can develop and run projects using the streamingproject, streamingprojectclient, and streamingcompiler commands. For a full list of Event Stream Processor utilities, see the SAP Event Stream Processor: Utilities Guide.
