Andrzej Bialecki commented on SOLR-13003:
------------------------------------------
This patch includes the following changes:
* adds Accountable to FastLRUCache
* adds tighter tracking of both key and value sizes in all Solr caches. This
builds on the changes in LUCENE-8855.
* some refactoring to put common constants in one place and to use more
realistic defaults for unknown objects / query types.

> When using the maxRamBytes parameter with the queryResultCache directive, we

> is configured.
> Please see attached VisualVM output which shows the retained size is about
> 1.5gb, but the maxRamBytes is set to 64mb.
