Robert Joseph Evans commented on STORM-1190:
--------------------------------------------
Wrong Robert Evans by the way. Sadly my name is just way too common.
If you look at the graph of CPU utilization

under heavy load the CPU utilization was smaller, so I didn't think it would
be too big of an issue. I plan on doing some more profiling to see if I can
understand where that load is coming from at low throughput to hopefully let us
all have our cake and eat it too.

> Key: STORM-1190
> URL: https://issues.apache.org/jira/browse/STORM-1190
> Project: Apache Storm
> Issue Type: Bug
> Components: storm-core
> Affects Versions: 0.11.0
> Environment: 10x (CoreOS stable (766.4.0) / k8s 1.0.1 / docker
> running on Azure VMs)
> Reporter: Michael Schonfeld
> Priority: Critical

> We've been running Storm's snapshots on our production cluster for a little
> while now (that back pressure support really helped us), and we've noticed a
> sudden spike in system load when going from
> commit@ba1250993d10ffc523c9f5464371fbeb406d216f to the current latest
> commit@c12e28c829fcfabc0a3a775fb9714968b7e3e349. Both versions were running
> the exact same topologies, and there was no significant change in workload.
> Not exactly sure how to even begin to debug this, so we ended up just rolling
> back. Thoughts?
> Stats screenshots attached
