10.2.3 Notes about using multiple caches
Note the following when you use multiple caches:
-
Fine-tuned operations cannot be performed for the caches individually, because the types of operations available to individual caches are limited.
-
The number of cache-related resources increases.
-
Performance might be affected adversely due to garbage collection because the size of the Java heap used by one process increases.
If there are too many caches, you can use the following methods to reduce the number of caches:
-
Split the cluster instead of using multiple caches in the same cluster.
-
When the same key name is used in different data items, use multiple groups, not multiple caches.
