You can configure flush latency to process data in real time. A real-time session reads, processes, and writes data to targets continuously. Flush latency determines how often the PowerCenter Integration Service flushes data from the source.

When you configure real-time flush latency and configure the session to use source-based commits, the PowerCenter Integration Service commits IDocs to the target using the source-based commit interval and the real-time flush latency interval. The PowerCenter Integration Service uses the number of IDoc records or control segments for the commit interval.
