Hello, we're successfully using solr in our application for a few months now. Recently we've got asked if there is a possibility of having multiple master nodes (in case of some disaster happening in one of server locations). Basically what we want to do is having a few master nodes running at the same time which then could automatically pick up the work if one is not responding. For now we have decided to go with a complete master node replication (basically on machine level) running the whole time and ready to be plugged in to the live system via DNS configuration if something wrong happens to the "real" master.
Latest stackoverflow post about that is nearly 6 years old ( http://stackoverflow.com/questions/6362484/apache-solr-failover-support-in-master-slave-setup) so I was wondering if something has changed since then or are there any new solutions to the issue. Kind Regards, Dominik
