[hibernate-dev] JBoss Cache / Infinispan index copying in HSearch

Hi,

I'm reviving previous discussion.

I was thinking about possible ideas about this problem, but could I get some
directions and advices where to start. Does JBC/Infinispan job should be to
store index (kind of shared directory) copied from master, and makes it
available for slaves? Or maybe better idea is to write custom
DirectoryProvider based on JBC/Infinispan with passing over current
master/slave directory providers?

Cheers,
Lukasz
