> 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.
