[jira] [Commented] (SOLR-9176) Legacy Faceting Term Enum Method
Regression
[ https://issues.apache.org/jira/browse/SOLR-9176?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15310952#comment-15310952 ]
Alan Woodward commented on SOLR-9176:
-------------------------------------
Patch looks good, I'm running tests now.
I think we could also add a test that runs faceting on a bunch of different field types with various methods added, and checks the debug output to see which method was actually used.

> It is not possible to use Term Enum as a faceting method, for numeric and single valued fields ( org.apache.solr.request.SimpleFacets ) .
> We personally verified that there are use cases when this is bringing a quite big performance regression ( even with DocValues enabled) .
> In the mailing list from time to time people complain about a regression happening with the term enum method, but actually it is more likely to be the automatic forcing of FCS.
> Forcing FCS in co-op with the famous regression that happened in SOLR-8096 could be confused as a term Enum regression.
