Is there a way to retrieve data (or dump it all) from the ENTITIES cache that was filled by a Hibernate OGM persist?

For example, as you can see, the below prints out 0 for the cache size, but I would think it should be at least one, since Hibernate OGM successfully entered a value


EntityManager em = emf.createEntityManager();
Breed collie3 = new Breed();
collie3.setName( "Sammyx" );
em.persist( collie3 );
Dog dina = new Dog();
dina.setName( "Dinax" );
dina.setBreed( collie3 );

em.persist( dina );
Long dinaId = dina.getId();
em.flush();
em.close();
tm.commit();
CacheManager manager = new DefaultCacheManager();
System.out.println("--> " + manager.getCacheNames());
Cache localCache = manager.getCache("ENTITIES(dist_sync)");
System.out.println("local cache = " + localCache.size());

RESULTS:

About to store dog and breed
local cache = 0
Found dog Dinax of breed Sammyx

Hi, I'm assuming that's an Infinispan CacheManager?

There are several things to consider:

- When Infinispan is configured with DIST_SYNC the size() operator is not accurate, it will only show the size of the local node, not the whole content of the data grid.

- you're creating a new CacheManager, not taking the instance which OGM is using. That could work as long as this CacheManager connects to the other one, but you're effectively needing to rebalance the cluster: rebalancing is automatic but happens in the background, it likely didn't even finish connecting if you don't give it some wait time.

- the cachename must match exactly - not sure if that cache name is the one you've configured OGM to use?

It would be easier to extract the reference of the Infinispan cache from the emf.
