bq: How similar thing could be done in 4.9.1? That's not going to happen. More precisely, there is zero chance that anyone will take on that work unless it's a custom one-off that you hire done or develop internally. And even if someone took this on, it'd never be officially released.
IOW, if you want to try backporting it on your own, have at it but that'll be completely unsupported. One thing people have done is create two independent clusters, complete to separate ZK ensembles and have the indexing client send updates to both DCs. At that point it also makes sense to have them both serve queries..... Another choice is to have your system-of-record replicated to both DCs, and have the indexing process run in both DCs from the local copy of the system-of-record to the local Solr clusters independently of each other.
