@Retention(value=RUNTIME) @Target(value=METHOD) public @interface TopologyChanged
This annotation should be used on methods that need to be notified when the ConsistentHash
implementation
in use by the DistributionManager
changes due to a change in cluster topology. This is only fired
in a Configuration.CacheMode#DIST_SYNC
or Configuration.CacheMode#DIST_ASYNC
configured cache.
TopologyChangedEvent
otherwise a
IncorrectListenerException
will be thrown when registering your listener.
Note that methods marked with this annotation will be fired before and after the updated ConsistentHash
is installed, i.e., your method will be called twice, with Event.isPre()
being set to true as well
as false.
