public class MetadataEhcacheAutoConfiguration
extends Object

Configuration for engaging default Broadleaf support for Ehcache in the Metadata service.

This configuration uses a weighted budgeting system to distribute a fixed memory footprint across all metadata cache regions. The following table illustrates the default distribution based on a 5MB Heap and 5MB Off-Heap budget:

Cache Name	Weight	Est. Size	Heap Entries (90%)	Off-Heap MB (90%)
Metadata Component	100%	20 KB	~230	4.5 MB

Note: The remaining 10% of each weighted budget is allocated to a companion "Keys" region used by the CacheStateManager for eviction tracking.
