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. Event Stream Processor also provides an adapter toolkit, several SDKs, and an internal adapter API that enable you to write a custom adapter.

• 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.
• 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 that are currently available from SAP use the log4j API to log errors, warnings, and debugging messages.
• Internal and External Adapters
  An adapter that runs as part of the Event Stream Processor Server is called an internal adapter. An adapter that runs as a separate process is called an external adapter.
