loadOnStartup=false doesn't appear to work for Solr 6.6
Hello,
I'm not using SolrCloud and want to have some cores not load when Solr
starts up.
I tried loadOnStartup=false, but the cores seem to start up anyway.
Is the loadOnStartup parameter still usable with Solr 6.6 or does the
documentation need updating?
Or Is there something else I need to do/set?
Tom

Thanks for bringing that to closure, I was worried!
At a low level, any time CoreContainer.getCore() gets called, the core
is loaded. If there are transient cores, then perhaps an old transient
core is aged out....
Best,
Erick

Thanks Erick,
Silly oversight on my part. I went into the admin panel and used the core
selector to view information about the core and it was running.
I did some more thinking about it and restarted solr and looked at the core
admin panel where I could see that the startTime was "-".
So the problem is operator error. I didn't think about how the core
selector actually sends a query to the core to get stats, which of course
starts the core.

Tom:
That hasn't been _intentionally_ changed. However, any request that
comes in (update or query) will permanently load the core (assuming no
transient cores), and any request to the core will autoload it. How
are you determining that the core hasn't been loaded? And are there
any background tasks that could be causing them to load (autowarming
in solrconfig doesn't count).
