Subject how to replicate Solr Cloud
Date Tue, 25 Jun 2013 17:07:42 GMT
We are going to have two datacenters, each with their own SolrCloud and
ZooKeeper quorums. The end result will be that they should be replicas of
each other.

One method that has been mentioned is that we should add documents to each
cluster separately. For various reasons, this may not be ideal for us.
Instead, we are playing around with the idea of always indexing to one
datacenter. And then having that replicate to the other datacenter. And
this is where I am having some trouble on how to proceed.

The nice thing about SolrCloud is that there is no masters and slaves. Each
node is equals, has the same configs, etc. But in this case, I want to have
a node in one datacenter poll for changes in another data center. Before
SolrCloud, I would have used slave/master replication. But in the SolrCloud
world, I am not sure how to configure this setup?

Or is there any better ideas on how to use replication to push or pull data
from one datacenter to another?

In my case, NRT is not a requirement. And I will also be dealing with about
3 collections and 5 or 6 shards.
