The Disk agents collect and forward batches of files on local file systems and are available in batch and real-time workflow configurations.
The configuration of the Disk agents are different in real-time workflows compared to batch workflows, since the former do not have built-in batch boundaries. Batch workflows also provide built-in support for transaction safety and enables additional features in the Disk agents that are not available in real-time workflows.
For more information about the difference between batch and real-time workflows, see 3.1.1 Workflow Types.
