Infinispan configuration - infinispan

Question

I am bit confused reading Infinispan guide.
I want to have two clustered caches, propably must have separate jgroups files to have different multicast addresses, but should there be only one cache containter?

Answer 1

You don't need to have a separate jgroups file for each clustered cache. Simply configure the transport element of the cache-container, and then you can define any number of caches in that cache-container.

Answer 2

Different multicast addresses are only needed if you want cache containers to form different clusters. I think the confusing thing here is that you can define multiple stack-file elements in JGroups but you can only really specify a single cache-container element. The XSD is not precise enough, but the parser within the code assumes a single global configuration builder instance, hence a single cache container. So, if you want to create two separate cache containers, these should be currently defined in separate XML files.
