Hello.
SolrCloud has been out for a while now. However, there are still many installations running Solr4 in the traditional master-slave setup. Currently, the Solr Master is the single point of failure of most master-slave deployment. This could be easily addressed by having : a- 2 independents Solr Masters running side-by-side and being fed simultaneously, b- all slaves configured with masterUrl=masterUrl01,masterUrl02 (needs to be implemented) c- by default, masterUrl01 will be used by all slaves. d- When the slaves catch an exception (like NoRouteToHostException or ConnectionTimedOutException etc), they will retry a couple of times before switching to using masterUrl02. I suppose you have thought about this issue before. So I would like to know whether there are issues with such a simple solution. This could also help deploy Solr across 2 different data-centers. Thank you very much. Arcadius.
