Subject [jira] [Commented] (SOLR-7191) Improve stability and startup performance of SolrCloud with thousands of collections
Date Wed, 04 Mar 2015 23:10:38 GMT

    [ https://issues.apache.org/jira/browse/SOLR-7191?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14347746#comment-14347746

Erick Erickson commented on SOLR-7191:
--------------------------------------

Just throwing this out there, but tangentially related is the whole "Lots of cores" thing.
It's really an open question to me how much effort into supporting either a zillion collections
(or even a zillion cores).

The LotsOfCores code was written without considering how to support it in SolrCloud. I'm quite
sure it'd be "interesting" to support. I'm explicitly _not_ advocating whether it be supported
in SolrCloud, it'd have to be thought out pretty carefully and my instinct is that it wouldn't
be worth the effort.

FWIW

> A user on the mailing list with thousands of collections (5000 on 4.10.3, 4000 on 5.0)
is having severe problems with getting Solr to restart.
> I tried as hard as I could to duplicate the user setup, but I ran into many problems
myself even before I was able to get 4000 collections created on a 5.0 example cloud setup.
 Restarting Solr takes a very long time, and it is not very stable once it's up and running.
> This kind of setup is very much pushing the envelope on SolrCloud performance and scalability.
 It doesn't help that I'm running both Solr nodes on one machine (I started with 'bin/solr
-e cloud') and that ZK is embedded.
