[jira] [Resolved] (SOLR-10478) cache 'size' is ignored if 'maxRamMB' is set -- confusing

     [ https://issues.apache.org/jira/browse/SOLR-10478?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Cassandra Targett resolved SOLR-10478.
--------------------------------------
    Resolution: Won't Fix

This issue has been open for potential documentation improvements, but none have been suggested. The Ref Guide now is pretty clear on precedence with these params:

{noformat}
When both size and maxRamMB limits are specified the behavior will differ among implementations: in CaffeineCache the maxRamMB limit will take precedence and the size limit will be ignored, while in LRUCache and FastLRUCache both limits will be observed, with entries being evicted whenever any of the limits is reached.

> I thought perhaps I could set both {{size}} and {{maxRamMB}} and Solr would use both.  Nope; apparently {{maxRamMB}} has precedence.  Solr should log a warning or even throw an error if the user does this.
