optimization - Solr Trigger Optimize And Check Progress From Java Code -

from topic there 2 ways trigger solr optimize java code.
either sending http request, or using solrj api.
how check progress of it?
say, api returns progress of optimize in percentage
or strings running/completed/failed.
there such api?

yes, optimize() in solrj api sync method.
here used monitor optimization progress.
