Mark Miller commented on SOLR-4816:
-----------------------------------
bq. this "high priority" ... Jira ... is still listed as "Minor".
My personal priority list has nothing to do with the severity in JIRA for this
issue. I'm assigned and working on this - surprising or not.
I have stated that this is an important issue that is on the road map and that
it is high priority for me to get into 4.5. Nothing has changed.

> 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;
