--------------------------------------
Summary: Add option to customize badness_threshold in dynamic
endpoint snitch
Key: CASSANDRA-13679
URL: https://issues.apache.org/jira/browse/CASSANDRA-13679
Project: Cassandra
Issue Type: Improvement
Reporter: Simon Zhou
Assignee: Simon Zhou
Attachments: Screen Shot 2017-07-07 at 5.01.48 PM.png
I'm working on tuning dynamic endpoint snitch and looks like the default value
(0.1) for Config.dynamic_snitch_badness_threshold is too sensitive and causes
traffic imbalance among nodes, especially with my patch for CASSANDRA-13577. So
we should:
1. Revisit the default value.
2. Add an option to allow customize badness_threshold during bootstrap.
This ticket is to track #2. I attached a screenshot to show that, after
increasing badness_threshold from 0.1 to 1.0 by using patch from
CASSANDRA-12179, the traffic imbalance is gone.
