Andrzej Bialecki commented on SOLR-13558:
------------------------------------------
This patch implements dynamic modification of limits of all Solr cache implementations, using an API similar to the one proposed in the parent issue.

> 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.
