What sort of replication are you using? SolrCloud? I believe that Zookeeper doesn't like high-latency setups, thus SolrCloud isn't, of itself, a good way to replicate across datacentres. Traditional master/slave should be fine in that setup, or the cross-datacentre replication (CDCR) work that has been done recently might help you. Not so sure what state that is in - I'm sure Erick can say more! Upayavira
