Description

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.
