Class NearCacheManager

java.lang.Object
  com.atlassian.confluence.cache.hazelcast.nearcache.NearCacheManager

@Internal
public class NearCacheManager
extends java.lang.Object

Creates near cache wrapper around distributed cache.

It does so by checking if near cache explicitly configured in #nearReferenceCacheNames) and if it is then all remote reads will be cached in locally.

Cache entry is removed when remove/expire/update event is received from distributed cache, or, if expire-after-write/expire-after-access timeout reached on local cache.

It's possible to have different max size and exiration policies for near caches. See {@link #createNearCacheSettings} for more details

Method Detail

initialize

public void initialize()

Initializes near caches for corresponding distributed caches. The reason to do that on class in this method of lazily is because of race condition on cache creation with loader in atlassian cache api. For every distributed cache listed in nearReferenceCacheNames corresponding ehcache will be created for caching remote reads in local memory.
