Is anyone successfully running Solr 7x in cloud mode with thousands or more of

That many collections will overwhelm SolrCloud. This issue is marked as
fixed, but it's actually not fixed:
https://issues.apache.org/jira/browse/SOLR-7191
SolrCloud simply will not scale to that many collections. I wish I had
better news for you. I would like to be able to solve the problem, but
I am not familiar with that particular code. Getting familiar with the
code is a major undertaking.
Thanks,
