[hibernate-dev] Infinispan cache loaders in Hibernate Search

Infinispan offers several persistance stores to persist content of cache, i.e. based on file system, database, S3 amazon service. Is there some recommendation which one should be used as a default for Hibernate Search directory provider based on Infinispan cache? What about cache loaders configuration strategy: one cache store per node, one common store for all nodes, only single node allowed to write to persistance store. Maybe one common store is the right one. Cheers Lukasz Moren
