how to get cache store and get keys from it

matlach May 9, 2012 10:06 PM

Hello everyone,

I was wondering if, there is any way to get the cache configurated cache store ?

I've looked up in the AdvancedCache interface but found nothing.

Also, is there any way to get keys from store to do some processing on passivated entries ?

Tough the only method I see, is the one provided in : CacheLoader::Set<Object> loadAllKeys(Set<Object> keysToExclude)

to me, it would be actually quite nice to provide methods:

1. to get the actual count of keys in store,

2. to get the first x keys (max result)

3. to get the first keys 'between' y (min result) and z (max result)

most likely the hibernate/hibernate search interface permit it.

Big thanks,

You can use the following call to retrieve the cache store:

org.infinispan.loaders.CacheStore s = cache.getAdvancedCache().getComponentRegistry().getComponent(CacheLoaderManager.class).getCacheStore();

(https://github.com/infinispan/infinispan/blob/master/core/src/main/java/org/infinispan/loaders/CacheStore.java)

after that, you can call methods like s.containsKey(Object key), s.store(InternalCacheEntry entry), s.load(Object key)

InternalCacheEntry is an interface and has a few implementations, e.g. ImmortalCacheEntry.

Thanks Martin for pointing me out how to recover the cache loader ; really not obvious at the first start !
I guess I'll fill an enhancement request to ease manipulation of passivated entries.

Thanks again,
