10.4.6. ElementSizeAlgorithm - Eviction based on number of key/value pairs in a node

org.jboss.cache.eviction.ElementSizeAlgorithm controls the eviction based on the number of key/value pairs in the node. The most recently used nodes will be the first to evict with this policy. It has the following configuration parameters:
  • maxNodes - This is the maximum number of nodes allowed in this region. 0 denotes immediate expiry, -1 denotes no limit.
  • maxElementsPerNode - This is the trigger number of attributes per node for the node to be selected for eviction. 0 denotes immediate expiry, -1 denotes no limit.
  • minTimeToLive - the minimum amount of time a node must be allowed to live after being accessed before it is allowed to be considered for eviction. 0 denotes that this feature is disabled, which is the default value.
