Hi, I read the documentation about this feature over here<https://cwiki.apache.org/confluence/display/solr/Rule-based+Replica+Placement>. I did not get a very clear understanding of how this feature works and how I can configure it in Solr.
This is what I would like to achieve and am wondering if anyone has tried this feature and what their experience has been with it. If I would like to configure a rule to make sure that for every shard at-least one replica is assigned to each rack before more than one replicas are assigned to the same rack, how would that rule look like? For e.g If I have a collection with 2 shards and replication-factor: 2 and I have 3 racks say rack1, rack2, rack3, I want to make sure that at-least one replica is assigned to each rack. So the replicas in this case should be assigned as shard1_replica1: rack1, shard1_replica2:rack2, shard2_replica1:rack3 and shard2_replica2:<one of the 3 racks> It should not assign the replicas as shard1_replica1:rack1, shard1_replica2:rack1, shard2_replica1: rack2, shard2_replica2: rack2. In this case all the replicas of a shard are assigned to the same rack. This is not ideal and not good for HA reasons. Regards Suresh
