> Rebalancing relocates data from heavily loaded members to lightly loaded members. Currently Geode only supports manual rebalancing by issuing a gfsh command or a java function call. In most cases, the decision to rebalance is based on the size of the member. As Geode monitors the data size, it can also automatically trigger rebalancing. Auto-Rebalancing is expected to prevent failures seen in an unbalanced cluster more than with a manual rebalance.
