Hi, As far as I know CloudSolrServer is recommended to be used for indexing to SolrCloud. I wonder what are advantages of this approach over external load-balancer ? Let's say I have 4 nodes SolrCloud (2 shards + replicas) + 1 server running ZooKeeper. I can use CloudSolrServer for indexing or use load-balancer and send updates to any existing node. In former case it seems that ZooKeeper is a single point of failure - indexing is not possible if it is down. In latter case I can still indexing data even if some nodes are down (no data outage). What is better for reliable indexing - CloudSolrServer, load-balancer or you know some different methods worth to consider ?
Regards.
