6.4.2. Suppress State Transfer via JMX

State transfer can be suppressed using JMX in order to bring down and relaunch a cluster for maintenance. This operation permits a more efficient cluster shutdown and startup, and removes the risk of Out Of Memory errors when bringing down a grid.

When a new node joins the cluster and rebalancing is suspended, the getCache() call will timeout after stateTransfer.timeout expires unless rebalancing is re-enabled or stateTransfer.awaitInitialTransferis set to false.

Disabling state transfer and rebalancing can be used for partial cluster shutdown or restart, however there is the possibility that data may be lost in a partial cluster shutdown due to state transfer being disabled.
