Mark Miller commented on SOLR-7121:
-----------------------------------
bq. Without the regular expression, one would need separate configuration files
for separate collections which is somewhat of a pain to manage.
Couldn't you make the same argument for all of the config in solrconfig.xml?
It seems that all SolrCores in the same collection will want the same config,
and you usually would want to use different config for other collections if you
want any of it to vary.
> Solr nodes should go down based on configurable thresholds and not rely on
> resource exhaustion

> Currently, there is no way to control when a Solr node goes down.
> If the server is having high GC pauses or too many threads or is just getting
> too many queries due to some bad load-balancer, the cores in the machine keep
> on serving unless they exhaust the machine's resources and everything comes
> to a stall.
> Such a slow-dying core can affect other cores as well by taking huge time to
> serve their distributed queries.
> There should be a way to specify some threshold values beyond which the
> targeted core can its ill-health and proactively go down to recover.
> When the load improves, the core should come up automatically.
