Adding Advanced Features to a Project

Complete your project by adding more complex operations and expressions, reusable modules and named schemas, and custom adapters.

• Complex Queries
  Use the generic derived stream, derived window, and derived delta stream shapes to create more complex continuous queries in the Visual editor than the ones you can create with the simple query shapes.
• Modularity
  A module in SAP Sybase Event Stream Processor offers reusability; it can be loaded and used multiple times in a single project or in many projects.
• Stores
  Set store defaults, or choose a log store or memory store to determine how data from a window is saved.
• Flex Operators
  Flex operators are custom operators that let you write SPLASH scripts to operate on incoming events.
• Creating a Schema in the Visual Editor
  Create a shared schema object that can be referenced from any number of streams or windows.
• Setting an Aging Policy
  An aging policy can be set to flag records that have not been updated within a defined interval. This is useful for detecting records that may be "stale".
• Monitoring Streams for Errors
  Modify a project to use error streams to keep track of errors in other streams in the project.
• Guaranteed Delivery and Persistent Subscribe Pattern
  Guaranteed Delivery (GD) is a delivery mechanism that ensures that data continues to be processed from a stream to an adapter even if the Server fails, the destination (third-party server) fails, or the destination does not respond for a period of time.  
• Declaring a Parameter
  Create a new parameter.
