Choose the degree of customization your application requires.
When choosing a development scenario, note that they are all related. If you are developing a custom feed handler, you need to customize the messages and schema. Likewise, if you customize messages and schema, you need to modify the feed handler.
| Scenario | Description |
|---|---|
| Customize the RAP messages and schema |
Follow this process when adding a new table or column to the RAPCache and RAPStore. |
| Develop a custom feed handler |
Use the Publisher API, the logging API, and configuration files to develop and deploy a custom feed handler. |
| Customize the FAST feed handler |
Customize the FAST feed handler by writing a message handler plug-in. Follow this process when the incoming data stream is encoded in the FAST protocol. You can implement a subset of the Sybase FAST feed handler, process message types other than those defined in the Sybase FAST templates library, or perform different initialization, processing, or logging. |
