Sanne Grinovero commented on ISPN-7842:
---------------------------------------

I agree on the server vs domain metadata conflict raised by [~anistor].

For embedded mode, personally I hope all of the Cache configurations will be separated from the root CacheManager one day: as discussed in the past the "application level CacheManager" should be able to be automatically started (stopped) from a JVM scoped root via something like the FORK channel, or the equivalent at Infinispan level.

The same should happen for server: separation of configuration and lifecycle of caches needed for a specific application; in the server mode this could be similar to a multitenancy feature, to allow rolling upgrades / data migration of a specific set of caches belonging to one user/application.

My hope is that Cache configuration and its content metadata would still belong together, so making the above design sensible. Pretty much like tables and the table content in a RDBMs, what we're missing is the grouping of several tables in one logical database.

In short I agree this separation should happen but I don't think it's necessarily evil to have this specific metadata tied to a Cache, if we can agree that a "cut" of separation needs to be done somewhere between the Cache definition and say the JGroups configuration (or somewhere in between).

>             <indexed-entities>
>                <!-- annotated entity -->
>                <indexed-entity>org.infinispan.query.queries.faceting.Car</indexed-entity>

>                   <!-- the FQN of the class to index -->
