> This issue adds the following enhancements to CloudSolrServer's update logic:
> 1) Document routing: Updates are routed directly to the correct shard leader eliminating document routing at the server.
> 2) Optional parallel update execution: Updates for each shard are executed in a separate thread so parallel indexing can occur across the cluster.
> These enhancements should allow for near linear scalability on indexing throughput.
> Usage:
> CloudSolrServer cloudClient = new CloudSolrServer(zkAddress);
> cloudClient.setParallelUpdates(true);
> SolrInputDocument doc1 = new SolrInputDocument();
> doc1.addField(id, "0");
> doc1.addField("a_t", "hello1");
> SolrInputDocument doc2 = new SolrInputDocument();
> doc2.addField(id, "2");
> doc2.addField("a_t", "hello2");
> UpdateRequest request = new UpdateRequest();
> request.add(doc1);
> request.add(doc2);
> request.setAction(AbstractUpdateRequest.ACTION.OPTIMIZE, false, false);
> NamedList response = cloudClient.request(request); // Returns a backwards compatible condensed response.
> //To get more detailed response down cast to RouteResponse:
> CloudSolrServer.RouteResponse rr = (CloudSolrServer.RouteResponse)response;
