Shalin Shekhar Mangar commented on SOLR-7280: --------------------------------------------- What was the motivation behind changing the sorting logic? Can you please explain what use-cases does the new logic cover better? bq. The shards with least no:of replicas in down nodes and there is at least one live node waiting for replicas of this shard. If these nodes are in down nodes, it is no use bringing up a replica because, until those down nodes come up, that shard cannot be up This is flawed because with these rules, a shard which has exactly 1 replica in total and that too on the current node will always be chosen last. > Load cores in sorted order and tweak coreLoadThread counts to improve cluster > stability on restarts > --------------------------------------------------------------------------------------------------- > > Key: SOLR-7280 > URL: https://issues.apache.org/jira/browse/SOLR-7280 > Project: Solr > Issue Type: Bug > Components: SolrCloud > Reporter: Shalin Shekhar Mangar > Assignee: Noble Paul > Fix For: 5.2, 6.0 > > Attachments: SOLR-7280.patch, SOLR-7280.patch > > > In SOLR-7191, Damien mentioned that by loading solr cores in a sorted order > and tweaking some of the coreLoadThread counts, he was able to improve the > stability of a cluster with thousands of collections.
