Configure evictors
Evictors can be configured using the ObjectGrid descriptor XML file or programmatically.
For reference information on configuring evictors with XML, see ObjectGrid descriptor XML file.
- TimeToLive (TTL) evictor
WebSphere eXtreme Scale provides a default mechanism for evicting cache entries and a plug-in for creating custom evictors. An evictor controls the membership of entries in each BackingMap instance.
- Plug in a pluggable evictor
Since evictors are associated with BackingMaps, use the BackingMap interface to specify the pluggable evictor.
