I'm exploring SolrCloud for a new project, and have some questions based upon what I've found so far.
The setup I'm planning is going to have a number of multicore hosts, with cores being moved between hosts, and potentially with cores merging as they get older (cores are time based, so once today has passed, they don't get updated). First question: The solr/conf dir gets uploaded to Zookeeper when you first start up, and using system properties you can specify a name to be associated with those conf files. How do you handle it when you have a multicore setup, and different configs for each core on your host? Second question: Can you query collections when using multicore? On single core, I can query: http://localhost:8983/solr/collection1/select?q=blah On a multicore system I can query: http://localhost:8983/solr/core1/select?q=blah but I cannot work out a URL to query collection1 when I have multiple cores. Third question: For replication, I'm assuming that replication in SolrCloud is still managed in the same way as non-cloud Solr, that is as ReplicationHandler config in solrconfig? In which case, I need a different config setup for each slave, as each slave has a different master (or can I delegate the decision as to which host/core is its master to zookeeper?)
