Hi- I have been reading up on SolrCloud and it seems that it is not possible to have a cross-datacenter read-only slave anymore but wanted to ask here to be sure. We currently have a pre Solr 4.0 installation with the master instance in our US mid-west datacenter. The datacenter in Europe has read-replicas which pull data using solr.ReplicationHandler. We wanted to upgrade to SolrCloud. As far as I have been able to figure out, with SolrCloud you cannot have a read-only replica anymore. A replica has to be able to become a leader and writes against all replicas for a shard have to succeed. Because of the a strong consistency model across replicas, it seems that replicas cannot be across datacenters anymore.
So my question is, how can we have a read-ony replica in a remote datacenter in Solr 4.0+ similar to pre Solr 4.0? Is it not possible anymore without doing it all yourself? cheers, Tikoo
