[infinispan-dev] Native Infinispan Multimap support

Hi all, As you probably know, Will and I are working on the vert-x infinispan integration [1], where the primary goal is to make infinispan the default cluster management of vert-x. (yeah!) Vert-x needs support for an Async Multimap. Today's implementation is a wrapper on a normal Cache where only Cache Key's are used to implement the multi map [2]. This is not very efficient, so after trying some other alternative implementations [3] that don't fully work (injection not working), Will and I have come to the conclusion that it might be a good idea to start having our own native CacheMultimap. This first multimap won't support duplicate values on key's. As a quick start, the smallest multimap we need should implement the following interface : public interface CacheMultimap<K, V> { V put(K key, V value); Collection<V> get(K key); boolean remove(K key, V value); } CacheMultimapImpl will be a wrapper on a normal Cache, similar to [3]. We could add a new method in EmbeddedCacheManager.java <K, V> CacheMultimap<K, V> getCacheMultimap(String cacheName, boolean createIfAbsent); Implementation will create a cache as always and return a new CacheMultimapImpl(cache). What do you think ? Please fell free to suggest any other alternative or idea.
