Noble Paul commented on SOLR-7280:
----------------------------------
[[email protected]] why do you want to test with
{{createCollection(collection, "conf1", 1,
NodeConfigBuilder.DEFAULT_CORE_LOAD_THREADS_IN_CLOUD * 3)}}. Why not keep it at
the default {{8}}
{{ // we only need 1 node because we're going to be shoving all of the replicas
on there to promote deadlock}}
How do you plan to get a deadlock if you are only going to have one node? The
deadlock happens because a node waits for other nodes to come up and those
nodes wait for this node (directly or through a circular dependency)
> Load cores in sorted order and tweak coreLoadThread counts to improve cluster
> stability on restarts

> 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. We should explore some
> of these changes and fold them into Solr.
