---------------------------------------
Summary: Only calculate 1.0 + dynamicBadnessThreshold once per
loop in DynamicEndpointSnitch
Key: CASSANDRA-15798
URL: https://issues.apache.org/jira/browse/CASSANDRA-15798
Project: Cassandra
Issue Type: Bug
Components: Messaging/Internode
Reporter: Jordan West
Assignee: Jordan West
The change to make dynamicBadnessThreshold volatile and mutable in
https://issues.apache.org/jira/browse/CASSANDRA-12179 could have minor
implications for the performance of this code:
https://github.com/apache/cassandra/blob/trunk/src/java/org/apache/cassandra/locator/DynamicEndpointSnitch.java#L216.
Its better to calculate this once before the loop starts, which has the added
benefit that the value is stable throughout the calculation as well.
