[jboss-jira] [JBoss JIRA] Commented: (JBAS-2637) Reduce memory footprint of HAPartition's state transfer
[ http://jira.jboss.com/jira/browse/JBAS-2637?page=comments#action_12341232 ]
Brian Stansberry commented on JBAS-2637:
----------------------------------------
Once streaming state transfer is in place (JBAS-3515), that's the mechanism to ensure
large states transfer effectively.
Also, in AS 5 only HASessionState uses ClusterPartition state transfer.
Reduce memory footprint of HAPartition's state transfer

Key: JBAS-2637
URL: http://jira.jboss.com/jira/browse/JBAS-2637
Project: JBoss Application Server
Issue Type: Feature Request
Security Level: Public(Everyone can see)
Components: Clustering
Reporter: Brian Stansberry
Assigned To: Brian Stansberry
Original Estimate: 3 hours
Remaining Estimate: 3 hours
HAPartitionImpl's state transfer mechanism marshalls state to a byte[] using
java.io.ByteArrayOutputStream. This memory-inefficient, as BAOS.toByteArray() makes a
copy of the internal byte[]. Need to move class
org.jboss.cache.util.ExposedByteArrayOutputStream to jboss-common and use it instead.
