Adrien Grand updated SOLR-3486:
-------------------------------

    Attachment: SOLR-3486.patch

This patch makes the maximum memory size of LRUCache configurable. It would be nice to add the same feature to the concurrent caches although I expect it to be a little more tricky.

> It is currently possible to configure the sizes of Solr caches based on the number of entries of the cache. The problem is that the memory size of cached values may vary a lot over time (depending on IndexReader.maxDoc and the queries that are run) although the JVM heap size does not.
> Having a configurable max size in bytes would also help optimize cache utilization, making it possible to store more values provided that they have a small memory footprint.
