This is about JBCACHE-64

Motivation

To be able to configure caches on a per-region basis.

What can be configured per-region?

Currently (2.x) available:

• Eviction policies

• Class loaders

• State transfer

• PojoCache scoping

For JBCACHE-64 (3.0.0)

• Isolation level (see JBossCacheMVCC)

• Transactional behaviour

• REQUIRES_NEW, NONE, etc.

• Replication (SYNC/ASYNC, INVALIDATION, LOCAL)

• Cache loading

Classes

Defining regions

• An Fqn can define a Node which is the root of the region

• Regions within regions allowed

Configuration

• Each region to have a Configuration, which inherits from it's parent region (if region is within a region) or the cache-wide default (copies it)

• Some elements may be dynamic

• If changing on the fly, acquire an exclusive lock on all nodes in the region (and any sub-regions)

• Update interceptors on all nodes in the region accordingly

• Release exclusive locks

• Any eviction policy updates in a region will reset eviction queues!
