Annotation Interface EnableEviction.EvictionPolicy

Enclosing class:

EnableEviction

public static @interface EnableEviction.EvictionPolicy

Definition for a specific Eviction policy that can be applied to 1 or more Regions. An Eviction policy defines the maximum (a.k.a. threshold) along with ObjectSizer used to size Region entry values and the action applied when Region entries are to be evicted. Additionally, the Eviction policy defines the algorithm used (eviction based on entry count, JVM Heap percentage or system memory size used) to determine when an Eviction should occur.
