> 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:
