Before 7.x all replicas in SolrCloud were NRT type. And following rules were applicable: https://stackoverflow.com/questions/45998804/when-should-we-apply-hard-commit-and-soft-commit-in-solr and https://lucene.apache.org/solr/guide/7_5/updatehandlers-in-solrconfig.html#commit-and-softcommit
But having new TLOG and PULL replica types causing some mess in that explanations. >From Ref guide we have: " NRT is the only type of replica that supports soft-commits..." "If TLOG replica does become a leader, it will behave the same as if it was a NRT type of replica." Does it mean, that if we do not have NRT replicas in the cluster then autoSoftCommit section in solconfig.xml Ignored completely (even on TLOG leader)? <autoSoftCommit> <maxTime>60000</maxTime> </autoSoftCommit> Should we say that in autoCommit section openSearcher is always true in that case? <autoCommit> <maxDocs>10000</maxDocs> <maxTime>30000</maxTime> <maxSize>512m</maxSize> <openSearcher>false</openSearcher> </autoCommit> Does it mean that new Searcher always starts on all replicas when hard commit happens on leader? Some words in Ref Guide about new replica types in section #commit-and-softcommit seems to be usefull. -- Vadim
