Nikita Koksharov commented on HHH-5260:
---------------------------------------

>What I'm trying to understand is what is it that you're trying to gain out of having a different cache instance for each query region? Is it setting different >eviction settings for each query region? 

Exactly, Clader. You are right, I want to have this opportunity. 

>To be able to do something similar with Infinispan yeah, we'd need to implement a change similar to what you suggest, where each query is stored under a cache >instance with that region name. You'd then be able maxEntries, lifespan...etc and other type of eviction settings for that particular region

So what we waiting for? Just do it :)

> From Niktia Koksharov in https://jira.jboss.org/browse/ISPN-458:
> "In current implementation of hibernate-infinispan we can tune only entity and collection settings via hibernate.xml.cfg. But tuning in same way for queries needed too. In current version there are always the same cache region for all queries (look at org.hibernate.cache.infinispan.InfinispanRegionFactory.buildQueryResultsRegion) and it's incorrect. 
> In org.hibernate.cache.infinispan.InfinispanRegionFactory.buildQueryResultsRegion 
> Replace those lines: 
>         String cacheName = typeOverrides.get(QUERY_KEY).getCacheName(); 
>         CacheAdapter cacheAdapter = CacheAdapterImpl.newInstance(manager.getCache(cacheName)); 
> To: 
>         Cache cache = getCache(regionName, QUERY_KEY, properties); 
>         CacheAdapter cacheAdapter = CacheAdapterImpl.newInstance(cache); "
