AtomicHashMap & Filesystem based cache stores.

[ges]

Hi,

I'm trying to understand how atomicmaps & cache stores work. I've configured an async SingleFileCacheStore for a cache and are using AtomicMaps against this cache.

AtomicMapLookup.getFineGrainedAtomicMap(cache, key);

All my values are stored in the atomic map. This is how it is:

k1 -> k2 -> v

k1 is the key to the cache and k2 is the key to the AtomicMap.

What I find is that data never makes it to the Single File Cache Store. If I make the cache store write through (synchronous), then it makes it to the cache store.

I think I'm missing something critical here but I'm not sure what it is.

Thanks for your help.

I don't understand your example could you show the code how you put/get the values?

javascript:;final FineGrainedAtomicMap<K, V> am = AtomicMapLookup.getFineGrainedAtomicMap(cache, key);

am.put(amKey, amValue);

I've tried the above and also the code below.

final TransactionManager tm = cache.getAdvancedCache().getTransactionManager();

try {

   tm.begin();

final FineGrainedAtomicMap<K, V> am = AtomicMapLookup.getFineGrainedAtomicMap(cache, key);

  am.put(amKey, amValue);

   tm.commit();

} catch (NotSupportedException | SystemException | RollbackException | HeuristicRollbackException| HeuristicMixedException e) {

   e.printStackTrace();

}

This the my configuration for the cache:

final ConfigurationBuilder configurationBuilder = new ConfigurationBuilder();

configurationBuilder.transaction().transactionManagerLookup(new JBossStandaloneJTAManagerLookup()).persistence()..addSingleFileStore().ignoreModifications(false).async().enable().threadPoolSize(30).modificationQueueSize(1000000).preload(false);

The data is available in the cache and can be queried but it does not get persisted into the store.
