Optimise nodes for single elements ---------------------------------- Key: JBCACHE-1082 URL: https://jira.jboss.org/jira/browse/JBCACHE-1082 Project: JBoss Cache Issue Type: Feature Request Security Level: Public(Everyone can see) Affects Versions: 2.0.0.CR1 Reporter: Manik Surtani Assignee: Manik Surtani Fix For: 3.0.0.GA Attachments: ReplicatedPojoPerfTest.java, UnversionedNode.patch.txt Many use cases just place a single object in a Node. Rather than going through the memory and performance penalties of using Maps for a single entry, we should: 1) Create a reference to 2 Objects for key and value, as well as a Map. 2) Only initialise/construct the Map if Node.putAll() is called, or when Node.put() is called with a second key/value pair 3) Otherwise just hold the key/value pair as direct object refs. Would affect UnversionedNode and WorkspaceNodeImpl.
