[overlord-issues] [JBoss JIRA] (BAM-77) Backing store for active collections

Backing store for active collections ------------------------------------ Key: BAM-77 URL: https://issues.jboss.org/browse/BAM-77 Project: Business Activity Monitoring Issue Type: Feature Request Reporter: Gary Brown Assignee: Gary Brown Fix For: 1.0.0.M4 Although active collections generally represent a realtime transient snapshot of some relevant information, on occasions it may be necessary that all instances of a collection across a cluster are consistent, and complete (e.g. on a server startup situation). In this situations, the active collection would require some shared state mechanism (e.g. cache) to replicate their state. The issue is that each server in the cluster will attempt to update their instance of the collection, so this needs to be handled (e.g. before applying the change check that it is required - but this may require some synchronization). Due to the potential performance implications, this type of active collection should ideally only be used where infrequent updates are applied.
