I know that: when using SolrCloud we define the number of shards into the system. When we start up new Solr instances each one will be a a leader for a shard, and if I continue to start up new Solr instances (that has exceeded the number number of shards) each one will be a replica for each leader as a round robin process.
However when I read wiki there are two parameters: *replicationFactor *and * maxShardsPerNode. *1) Can you give details about what are they. If all newly added Solr instances becomes a replica what is that replication factor for? 2) If what I wrote is true about that round robin process what is that * maxShardsPerNode*? How can be more than one shard at the system I described?
