Max Shonichev commented on IGNITE-8078:
---------------------------------------
[~dmagda] in current implementation, enabling metrics per-cache, instead of
per-cachegroup, when number of caches and partitions is high (4k/32k), simply
brings grid down, so IMO we really should move getRebalancingPartitionsCount()
out of CacheMetrics, because otherwise it is not suitable for production at all.
