[jira] [Commented] (IGNITE-2801) Coordinator floods network with
partitions full map exchange messages
[ https://issues.apache.org/jira/browse/IGNITE-2801?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15203937#comment-15203937 ]
Anton Vinogradov commented on IGNITE-2801:
------------------------------------------
Reproduced.
Started 10 nodes with 35 caches.
Gained 37 MB of GridDhtPartitionsFullMessage per minute -> 49 Mb/s
Rrough multiplication to 30 nodes & 65 caches (x6) gives exactly 300Mb/s

> Key: IGNITE-2801
> URL: https://issues.apache.org/jira/browse/IGNITE-2801
> Project: Ignite
> Issue Type: Bug
> Components: cache
> Affects Versions: 1.5.0.final
> Reporter: Denis Magda
> Assignee: Anton Vinogradov
> Priority: Critical
> Labels: community, important
> Fix For: 1.6

> Attachments: basic_node.nps, basic_node.png, coordinator.nps, coordinator.png

>
> It is detected that the more machines in the cluster we have and the more caches are started then the more outgoing traffic is produced by a coordinator node.
> As an example in the current deployment
> - 30 nodes;
> - 67 caches;
> - caches are empty and the cluster is not used at all (idle).
> the coordinator constantly uses 300 Mbit/s of outgoing traffic. In contrast each other node shows constant 10 Mbit/s usage of incoming traffic.
> Most likely the reason is that the coordinator indefinitely sends partitions full map for all the caches to all the nodes. This shouldn't happen.
> Need to debug the reason of the issue and fix it.
> Attached snapshots taken from the coordinator and on of cluster's nodes. Probably they would help.
