Introduction

SAP® Sybase® Event Stream Processor includes an extensive set of input and output adapters that you can use to subscribe to and publish data. Additional specialized adapters for Event Stream Processor are available from SAP® as optional add-ons. You can also write your own adapters to integrate into the ESP Server and design them to handle a variety of external requirements that the standard adapters cannot manage.

Event Stream Processor provides an adapter toolkit for building custom external (Java) adapters.

Event Stream Processor also provides a variety of SDKs that you can use to build custom external adapters in a number of programming languages, such as C, C++, Java, and .NET (C#, Visual Basic, and so on). For versions supported for SDKs, see the Installation Guide.

• Input and Output Adapters
  Input and output adapters enable Event Stream Processor to send and receive messages from dynamic and static external sources and destinations.
• Managed and Unmanaged Adapters
  An external adapter can be developed and configured to support running in managed-only mode, unmanaged-only mode, or to support both modes.
• Subscribing to Data with Input Adapters
  Subscribe to data from an external datasource and use an input stream or window to send the data to Event Stream Processor.
• Publishing Data with Output Adapters
  Use an output stream or window to publish data from Event Stream Processor to an external datasource.
• Editing Adapter Property Sets
  Adapter property sets are reusable groups of properties that are stored in the project configuration file. Use the ESP Studio CCR Project Configuration editor to define adapter property sets and store them in the associated .ccr file.
• Adapter Logging Configuration
  Specific adapters currently available from SAP use the log4j API to log errors, warnings, and debugging messages.
