When UseAck is set, by how much is the wait queue increased?

1. Twice the MaxQueueSize

2. 1.5 times the MaxQueueSize

3. 3 times the MaxQueueSize

4. 4 times the MaxQueueSize

The correct answer is: 3 times the MaxQueueSize

When UseAck is enabled, it adjusts how data is acknowledged in the system and ultimately affects the wait queue size. Specifically, it increases the wait queue to three times the MaxQueueSize. This adjustment is made to accommodate scenarios where acknowledgments are necessary to ensure data is processed reliably, especially in high-throughput environments. The rationale behind this increase is to provide a buffer that can handle spikes in data ingestion without overwhelming the system. By expanding the wait queue to three times the MaxQueueSize, it allows for greater flexibility and ensures that incoming data can be queued effectively while waiting for processing and acknowledgment. This adjustment helps maintain performance and reliability, as it mitigates the risks associated with data loss during periods of high load. Thus, the increase of the wait queue to three times the MaxQueueSize when UseAck is activated is a critical feature for managing data flows efficiently within Splunk's architecture.
