As I've described previously, I have an application deployed that uses 8 remote cache servers using the JDBC disk cache (each sitting on top of a MySQL instance). JCS handles expiration, failover, and periodic MySQL optimization. The setup is divided into 4 nodes, each with a primary and a failover remote server. The clients are not configured to receive callbacks. The data is partitioned into 4 groups, each corresponding to a node. The keys are numeric. To determine the partition, you simply take the modulus of the key and the number of partitions. In my case, this gives you a number between 0 and 3. I use this as a suffix to the region name. The cache.ccf file has 4 regions defined: myregion_0, myregion_1, myregion_2, myregion_3. Each one of these regions is configured to use a different remote cache node--that is, each has a different remote auxiliary configuration. The entire system is setup to cache 12 GBs of short lived data every hour. This setup is designed to handle several million large items.
