Input and Output Adapters
Input and output adapters enable SAP Event Stream Processor to send and receive messages from dynamic and static external sources and destinations.
External sources or destinations can include:
-
Data feeds
-
Sensor devices
-
Messaging systems
-
Radio frequency identification (RFID) readers
-
E-mail servers
-
Relational databases
Input adapters connect to an external datasource and translate incoming messages from the external sources into a format that is accepted by the ESP Server. Output adapters translate rows that are published by Event Stream Processor into message formats that are compatible with external destinations and send those messages downstream.
The following illustration shows a series of input adapters that translate messages from a temperature sensor, bar code scanner, and a Java Message Service (JMS) cloud into formats that are compatible with Event Stream Processor. After the data is processed using various queries within Event Stream Processor, output adapters convert the resulting rows into updates that are sent to an external database server, e-mail server, and Web services dashboard.
