ess_ that segment is < 5G. See LUCENE-7976. Or you explicitly set > >>> numSegments on the optimize command. > >>> > >>> So if you can reliably reproduce this, it’s probably worth a JIRA…... > >>> > >>>> On Mar 8, 2019, at 11:21 AM,

solr 7 optimize with Tlog/Pull replicas

finished optimization to a single segment, however all the leader replicas still have multiple segments. Previously inn the all NRT replica cloud, I see optimization is triggered on all nodes. Is the optimization process different with Tlog/Pull replicas? Best, Wei

TLOG+Pull replicas

Hi, I have a collection with 2 TLOG and 6 PULL replicas. When one of the pull nodes dies and is replaced with a new instance. It is being replaced by an NRT replica in the collection (the desired action is to be replaced by a PULL replica). collection is being created by collections?action=CREA
