[jboss-jira] [JBoss JIRA] (JBCLUSTER-44) Farm service startup performs way too many file transfers

Farm service startup performs way too many file transfers --------------------------------------------------------- Key: JBCLUSTER-44 URL: https://issues.jboss.org/browse/JBCLUSTER-44 Project: JBoss Clustering Issue Type: Bug Security Level: Public(Everyone can see) Environment: Jboss 4.0.2 final, Java 1.5.0_02 Reporter: Gabriele Garuglieri Assignee: Scott Marlow Fix For: Q2Y5 Attachments: JBCLUSTER-44-2.txt, JBCLUSTER-44.txt Suppose you have a cluster of N nodes and each node has A applications in the farm directory. Now you join node (N+1) to cluster, it receives N farmDeployments responses and pullNewDeployments() is called for each response. This means that each of the A applications is pulled from each of the N nodes for each call to pullNewDeployments(). Now there are two problems, there are (N**2)*A transfers and for large values of N and A this may become a problem. It can be even worse if the size of A files is large and there may be a huge latency in startup. Second, given that by definition the farming service keeps in sync all the member of the cluster, once the A files are pulled from the first cluster member then i have [(N**2)*A]-A useless transfers.
