What this boils down to, at the current state of the code, is whether an HttpSolrClient can operate properly against a SolrCloud. I *think* the answer is "yes" but have not found it so documented. Whether this is a good way to run a Solr client is another question. I *think* it is probably good enough. If we would *require* cloud mode, it would be much easier to set up and manage our data in Solr. There are a number of management API calls which only work in cloud mode, which could be used to create and configure collections instead of manually copying preconfigured cores into Solr's directory tree. Sharding could be done entirely within Solr using Time Routed Aliases instead of the way it was done in 6_x by fiddling with Solr's storage behind its back. (This bypasses the question of whether sharding is worth the hassle, considering the way we slice the data vs. the usual distribution of sharded records.) I think we could find willing a volunteer or two to do the work. What hasn't been found is enough people willing to discuss the issues that arise, and the broader questions of the ways in which DSpace uses Solr. -- Mark H.
