Mike Drob commented on SOLR-15762:
----------------------------------
bq. Then async option should be removed
Or rather, only the async mode should remain.
Let's take a moment to think about what we can do for folks already using
LRUCache on Solr 8... Should we remove it from 8.x entirely? Probably can't do
that. Warn on startup that it will not work with Join queries? Revert
SOLR-15555? Investigate if LRUCache can have an async mode as well?
