[jboss-jira] [JBoss JIRA] Updated: (JBCACHE-1365) Removing structural nodes during rollback is costly

Removing structural nodes during rollback is costly --------------------------------------------------- Key: JBCACHE-1365 URL: http://jira.jboss.com/jira/browse/JBCACHE-1365 Project: JBoss Cache Issue Type: Feature Request Security Level: Public(Everyone can see) Affects Versions: 2.2.0.GA Reporter: Mircea Markus Assigned To: Manik Surtani Priority: Minor Fix For: 2.2.0.GA within a Tx: when adding a new k,v pair to an *inexistent* node, the supporting tree structure is created within the transaction. In order to be able to rollback the these structural nodes, a CreateNode command is created for each such operation - not optimal as for each such commands a List is also built internally. The drawback for Fqn.size = n is -> n commands and n lists being created, which is a lot. solution: nodes are being create in PessimisticLockInterceptor, they should be passed in to the command itself so that it will be aware of them at rollback time, i.e. don't create a new command just for creating a new node.
