> Following up on this topic, this is what I have setup:
> 2 nodes in cluster (either lib mode or remote) - node-1 and node-2
> a cache setup as distributed, synchronous (dist_sync)
> cache.put("key", "value", -1, TimeUnit.MILLISECONDS, 2000, TimeUnit.MILLISECONDS);
> for (i = 0; i < 10; i++) {
> sleep(1000) // sleep 1 second
> cache.get("key");
> }
> Here is the weird thing, after a few gets, I'm starting to get null results.  This doesn't occur when there is only 1 node in the cluster.
> I'm suspecting that, w/ when accessing the data, it could be accessing 1 of the 2 nodes based on load balancing.
> cache.get("key") -> node-1  // 1s
> cache.get("key") -> node-1  // 2s
> cache.get("key") -> node-1  // 3s
> cache.get("key") -> node-2  // oops, this is already expired on node-2
> It would be nice to be able to make sure when accessing an entry from one node, the entry copies on other nodes are also "touched".
