Description

While working on SOLR-15475, I realized the SQL framework uses the StatsStream for non-bucketed aggregations (i.e. no GROUP BY) which makes a json.facet call under the covers. Investigate whether the StatsStream could use the tiered support for collection aliases that was added in SOLR-15036
