I was looking at this wiki and linked issues: http://wiki.apache.org/solr/LotsOfCores
they talk about a limit being 100K cores. Is that per server or per entire fleet because zookeeper needs to manage that? I was considering a use case where I have tens of millions of indices but less that a million needs to be active at any time, so they need to be loaded on demand and evicted when not used for a while. Also since number one requirement is efficient loading of course I assume I will store a prebuilt index somewhere so Solr will just download it and strap it in, right? The root issue is marked as "won;t fix" but some other important subissues are marked as resolved. What's the overall status of the effort? Thank you in advance, Aleksey
