org.scale7.cassandra.pelops.Selector
Interface used to define how nodes should be suspended for behaving badly. For example, if a node is reporting lots of corrupt connections then maybe it should be avoided for a while.

Implementations should indicate if a node is suspended by ensuring that {@link org.scale7.cassandra.pelops.pool.CommonsBackedPool.INodeSuspensionState#isSuspended()} returns trueuntil the node should no longer be considered suspended.

Any state required to determine if a node should be suspended should be stored in the nodes {@link PooledNode#getSuspensionState()}. Note that the suspension state may be null if the node has not been evaluated before.
Also note that the {@link #evaluate(CommonsBackedPool,PooledNode)}will be called by the scheduled tasks thread even when the node is currently suspended.

        final AtomicBoolean suspended = new AtomicBoolean(true);
        CommonsBackedPool pool = new CommonsBackedPool(
                AbstractIntegrationTest.cluster,
                AbstractIntegrationTest.KEYSPACE,
                config,
                new OperandPolicy(),
                new LeastLoadedNodeSelectionStrategy(),
                new CommonsBackedPool.INodeSuspensionStrategy() {
