[mod_cluster-issues] [JBoss JIRA] (MODCLUSTER-553) Failover targets should be chosen deterministically

Michal Karm Babacek created MODCLUSTER-553: ---------------------------------------------- Summary: Failover targets should be chosen deterministically Key: MODCLUSTER-553 URL: https://issues.jboss.org/browse/MODCLUSTER-553 Project: mod_cluster Issue Type: Bug Components: Native (httpd modules) Affects Versions: 1.2.13.Final, 1.3.5.Final Reporter: Michal Karm Babacek Assignee: Paul Ferraro Fix For: 2.0.0.Alpha1, 1.2.14.Final, 1.3.6.Final Under the following conditions: 1. A request arrives for a session with an unknown route 2. A request arrives for a session with a known route in an error state, or if the intended worker is unresponsive and needs to failover ... the failover target must be chosen in a deterministic way. This is meant to mitigate the situation where concurrent requests failover to different nodes and cause cluster-wide contention for the session. Given a consistent ordering of workers (e.g. lexographically), the failover target should be chosen by something like: hash code of session id % active worker count. -- This message was sent by Atlassian JIRA (v7.2.3#72005)
