[jira] [Commented] (SOLR-9633) Limit FastLRUCache by RAM Usage

    [ https://issues.apache.org/jira/browse/SOLR-9633?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15636910#comment-15636910 ]

---------------------------------------------

[~yseeley@gmail.com] - do you mind taking a look at this? Is the simple ram size based eviction logic fine or do we need to implement something fancier as we have for size based eviction?

> SOLR-7372 added a maxRamMB parameter to LRUCache to evict items based on memory usage. That helps with the query result cache but not with the filter cache which defaults to FastLRUCache. This issue intends to add the same feature to FastLRUCache.
