Description

Currently SolrCache limits are configured statically and can't be reconfigured without cache re-initialization (core reload), which is costly. In some situations it would help to be able to dynamically re-size the cache based on the resource contention (such as the total heap size used for caching across all cores in a node).

Each cache implementation already knows how to evict its entries when it runs into configured limits - what is missing is to expose this mechanism using a uniform API.
