[jira] [Created] (IGNITE-9337) VisorNodeDataCollectorTask may produce HUGE result in case of large cluster with many caches

Alexey Kuznetsov created IGNITE-9337:
----------------------------------------

             Summary: VisorNodeDataCollectorTask may produce HUGE result in case of large cluster with many caches
                 Key: IGNITE-9337
                 URL: https://issues.apache.org/jira/browse/IGNITE-9337
             Project: Ignite
          Issue Type: Task
          Components: wizards
            Reporter: Alexey Kuznetsov
            Assignee: Alexey Kuznetsov
             Fix For: 2.7


If cluster consists of 200 nodes and has 8000 caches (real deployment) it will produce

200 x 8000 =  1 600 000 instances of VisorCache (aprox 300b) on single invocation.

It will produce LARGE amount of data.

We can handle this by adding optional group name that should be collected instead of collecting all caches.
