[ https://jira.jboss.org/browse/JBPM-2031?page=com.atlassian.jira.plugin.sy... ] Alejandro Guizar updated JBPM-2031: ----------------------------------- Issue Type: Bug (was: Feature Request) Assignee: Alejandro Guizar Affects Version/s: jBPM 3.2.9 Priority: Critical (was: Minor) Description: Currently couple of bidirectional associations do not use inverse="true" on one-to-many side (collection) The examples are - ProcessInstance.instances - CompositeLog.children I'm sure there are more of them. Lack of inverse="true" results in additional "UPDATE" statement being issued by hibernate to create a relationship from a one-to-many side. This is not necessary when java code is updating both ends of an association. Some use-cases where lots of new processes are being created would see a performance improvement. CompositeLog logging overhead will decrease (only INSERT will be issued - no UPDATE) Please consider reviewing all of your bidirectional associations with respect to this optimization. was: Currently couple of bidirectional associations do not use inverse="true" on one-to-many side (collection) The examples are - ProcessInstance.instances - CompositeLog.children I'm sure there are more of them.

This one is *critical* in order to deliver the best possible performance, especially given the simplicity and innocuousness of the solution. -- This message is automatically generated by JIRA. - For more information on JIRA, see: http://www.atlassian.com/software/jira

Define one end as inverse or disable inserts and updates, where needed. The affected associations were: * Action.event * Node.superState and .arrivingTransitions * ProcessDefinition.definitions * Transition.from * Comment.token and .taskInstance * RuntimeAction.processInstance * TaskNode.tasks * ProcessLog.parent * ModuleInstance.processInstance Issue Time Tracking ------------------- Time Spent: 2 hours, 30 minutes Worklog Id: (was: 12423591) -- This message is automatically generated by JIRA. - For more information on JIRA, see: http://www.atlassian.com/software/jira
