The most trivial way of doing this is to define a failover node F of a failed node A as
the node to the right (or left, it doesn't matter) of the failed node in the jgroups
view. Also need to think of the view as a "ring".
E.g. if the jgroups view has addresses:
A
B
C
D
E
then node A fails over to node B, node B fails over to node C, node C fails onto node D,
node D fails onto node E, node E fails onto node A
Questions:
Is this sufficient for our needs?
Is there any sense in supporting multiple failover nodes for a single node? Or does that
make no sense?
Should the policy really be pluggable? (Probably yes)
