simple-election-policy is not sufficiently descriptive ------------------------------------------------------ Key: WFLY-8467 URL: https://issues.jboss.org/browse/WFLY-8467 Project: WildFly Issue Type: Enhancement Components: Clustering Affects Versions: 11.0.0.Alpha1 Reporter: Paul Ferraro Assignee: Paul Ferraro Fix For: 13.0.0.Beta1 simple-election-policy was originally a port of http://anonsvn.jboss.org/repos/jbossas/trunk/cluster/src/main/java/org/jb... It's time to revisit this. 1. The term "simple" doesn't at all describe how the policy elects the primary node. 2. "position" isn't intuitive either - until you realize that it is a reference to the underlying data structure. 3. Is the ability to specify the nth youngest or oldest node a realistic requirement? We can generalize this policy as doing 2 things: a. Sorts the candidates based on some criteria (e.g. age, name) b. Select the head of the sorted list This is logically equivalent to: members.stream().sort(comparator).findFirst(); Proposal: <age-election-policy sort="DESCENDING|ASCENDING"/> <name-election-policy sort="ASCENDING|DESCENDING"/>
