Flush Latency

Flush Latency

Flush latency determines how often the Integration Service flushes real-time data from the source. The lower you set the flush latency interval, the more frequently the Integration Service commits messages to the target. Each time the Integration Service commits messages to the target, the session consumes more resources and throughput drops.
Increase the flush latency to improve throughput. Throughput increases as you increase the flush latency up to a certain threshold, depending on the hardware and available resources.
