Thanks, Matthew. I tried debugging as you suggested. It seems that it is still doing atomic update instead of in-place update. I am not using SolrCloud, so I don't think that SOLR-13081 is applicable in my situation. I am using Solr 8.5.2 in standalone mode. I am not sure why in-place updates are still not getting triggered :(
