Tuning Solr cluster. One of the cons of a multi-shard schema is that if any replica is compromised, the shard leader is going to take more time than its peers to answer. This leads to the worst time response among the shards as Solr would wait for all the shards to answer before providing the final response. If a leader goes down, one of the other replicas is automatically elected as the new leader. When a document is sent to a Solr node for indexing, the system first determines which Shard that document belongs to, and then which node is currently hosting the leader for that shard. The document is then forwarded to the current leader for indexing. A Cluster is made up of one or more Solr Nodes, which are running instances of the Solr server process. Each Node can host multiple Cores. Each Core in a Cluster is a physical Replica for a logical Shard. Every Replica uses the same configuration specified for the Collection that it is a part of.

Based on benchmarks, Alfresco considers that a Solr Shard can contain up to 50 to 80 000 000 nodes. This is obviously not a hard limit, you can have a single Shard with 200 000 000 nodes but it is more of a best practice if you want to keep a fast and reliable index. Splitting a shard will take an existing shard and break it into two pieces which are written to disk as two (new) shards. The original shard will continue to contain the same data as-is but it will start re-routing requests to the new shards. The new shards will have as many replicas as the original shard. A soft commit is automatically issued. (c) Solr's commit command is time consuming. It works while you are playing with the sizes, but slows down the bulk process. You can either sends commits only in every Nth request (say after indexing 10 000 or 100 000 records), or even better you can set Solr's autoCommit feature which does it for you. Details here. ps.
