-----------------------------------
Summary: RouteOnContent causes high CPU usage with no data
Key: NIFI-1910
URL: https://issues.apache.org/jira/browse/NIFI-1910
Project: Apache NiFi
Issue Type: Bug
Affects Versions: 0.6.1
Environment: RPI3
Reporter: Andrew Grande
I have a RouteOnContent step in my flow which performs a simple regex match
with 2 outcomes (pass and unmatched).
However, I noticed that it is spinning with a lot of empty task cycles when
there is no data incoming at all. Moreover it causes 120% cpu usage spikes.
Confirmed multiple times via top by simply stopping and starting RouteOnContent.
