-----------------------------------
Summary: Add ability to turn off/on caches
Key: SOLR-9886
URL: https://issues.apache.org/jira/browse/SOLR-9886
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Reporter: Pushkar Raste
Priority: Minor
There is no elegant way to turn off caches (filterCache, queryResultCache etc)
from the solrconfig. When I tried setting size and initialSize to zero, it
resulted in caches of size 2. Here is the code that overrides setting zero
sized cache.
https://github.com/apache/lucene-solr/blob/master/solr/core/src/java/org/apache/solr/search/FastLRUCache.java#L61-L73
Only way to disable cache right now is by removing cache configs from the
solrConfig, but we can simply provide an attribute to disable cache, so that we
can override it using a system property.
