[hibernate-dev] Hibernate Search: Infinispan DirectoryProvider

Hi all, I'd like to merge the Infinispan DirectoryProvider soon: The code is trivial as it was designed primarily for Search, but some points need to be discussed: 1) Dependencies 1A) Transaction implementation: It does require Infinispan modules, most are transitive dependencies of <groupId>org.infinispan</groupId> <artifactId>infinispan-lucene-directory</artifactId> but it also requires a transaction manager implementation, which is not enforced by infinispan as any implementation will do. Shall we "suggest" one as optional dependency? This is going to add many dependencies, but we need something at least for tests. 1B) JGroups Infinispan depends on newer JGroups version than the one currently tested by the jgroups backend. I'd expect the new version to work the same, but are we going to explicitly depend on the same version of Infinispan? 2) Infinispan initialization A single CacheManager should be shared across many caches; in practice while I'd suggest to use a different cache per index we even do support more than one index in the same cache. At least a configuration property would be needed to point the CacheManager initialization to an Infinispan configuration file - which in turn will lilkely point to a JGroups configuration file. This configuration property could be global or "directory scoped" like we do for other properties but that would be complex. I'd suggest a single global CacheManager configuration - which will trigger a CacheManager initialization in the SearchFactory - and have different Directories be able to select the cache name and index name they want to use; (If two directories use the same cache and same index name they are sharing the same index) It would look like: hibernate.search.infinispan_configuration lucene-cluster-conf.xml hibernate.search.default.directory_provider org.hibernate.search.store.InfinispanDirectoryProvider hibernate.search.default.cache_name defaultLuceneIndexes hibernate.search.Animal.cache_name AnimalsLuceneIndex Sanne
