Transporter Modules

A transporter module is the interface that interacts with external data sources by obtaining data from a data source or outputting data to a data destination.

SAP Event Stream Processor supports two types of transporters: row-based and stream-based.

Row-based transporters obtain and output data in row format, such as a database transporter. These transporters work with AdapterRow instances, which are containers for one or more records or rows as they flow from one module (transporter, formatter, or ESP connector) to the next. You can add multiple records as objects within a List of a single AdapterRow object. The AdapterRow has a timestamp and block flags that control how its records are communicated to and from Event Stream Processor. See Event Blocks in the SAP Event Stream Processor: CCL Reference for additional details.

Stream-based transporters deal with streaming data, such as a socket transporter. These transporters work with ByteStream or ByteBuffer instances, which represent a continuous stream of data.
