> The set of cluster rebalancing properties below must be maintained and provided by {{IgniteConfiguration}},
so an administrator will be able to tune the cluster rebalance behaviour depending on used
hardware (e.g. the different hardware can have different maximum transmission unit (MTU) and
it's strongly recommended to use specific rebalanceBatchSize for each cluster environment).
> Currently, there is no way to change these properties for already created persistent
caches.

CPU. */
