             Summary: DynamicCacheChangeBatch invokes partition validation for all caches
                 Key: IGNITE-13353
                 URL: https://issues.apache.org/jira/browse/IGNITE-13353
             Project: Ignite
          Issue Type: Bug
          Components: cache
            Reporter: Sergey Uttsel
            Assignee: Sergey Uttsel
         Attachments: mihi-gridmanager.out, test22.png

Right now, DynamicCacheChangeBatch triggers partition validation for all caches. It can (and
most possibly it will) show inconsistency between partitions in case of using DataStreamer.
It will lead to the data rebalance, while it's not needed - updates should be streamed to
backup nodes after some time due to asynchronous behavior of DataStramer

In the attached log file cache was created at 1:33, it led to the partitions evictions right
after that and to the rebalance at ~2:36(they have rebalanceDelay = 1hour). This behaviour
led to these 2 drops almost to zero in write operations:
