Confluence plugin cache will not reset after configured time exceeded

Hi,

Im trying to use the build in caching mechanism in confluence (CacheManager) to cache some processing done is servlets. 
I used the following doc as reference:
https://developer.atlassian.com/confdev/development-resources/confluence-developer-faq/how-do-i-cache-data-in-a-plugin

The problem is that the cache doesn't seem to expire after 30 minutes (or any other time frame  I try to set in the configuration).
Does anyone else encountered this issue? Is this doc up to date?

Im using confluence 5.7.4 I've also spotted this issue in 5.8.4


Cheers,

Hi Aviram,

I had this issue too. At the end I set expireAfterAccess and expireAfterWrite. Clean cache plugins and everything is working as expected.

My cache settings

public CacheSettings getCacheSettings(){
		
		CacheSettingsBuilder cacheSettings = new CacheSettingsBuilder();
		
		cacheSettings.maxEntries(1000)
		.expireAfterAccess(0L, TimeUnit.MILLISECONDS)
		.expireAfterWrite(12, TimeUnit.HOURS)
		.flushable();
		
		return cacheSettings.build();
	}

That worked! Brilliant! Thanks! I hope Atlassian will update their docs soon, I can see a lot of people not even aware they have this issue.

Hi, got another question... does the cache key has anything to do with the cache aside for storage purposes? meaning, I don't have to use it in the "load" function right? can I just use global set fields of the class instead? Thanks!
