--------------------------------
Summary: Investigate performance when queues are swapping heavily
Key: NIFI-1281
URL: https://issues.apache.org/jira/browse/NIFI-1281
Project: Apache NiFi
Issue Type: Task
Components: Core Framework
Reporter: Mark Payne
Fix For: 0.5.0
If we have a queue that has a huge amount of swapping going on (in and out),
the ability to pull records from that queue is poor. When running a test, we
had a producer continually pushing records into a queue with no backpressure.
The consumer was very fast until swapping started to occur. At that point, the
ability to consume dropped to only a few thousand events/second. Stopping the
producer provided much better performance on the consuming side, which is
problematic.
