             Summary: create SolrCloudDIHWriter to speedup DataImportHandler on SolrCloud
                 Key: SOLR-9908
                 URL: https://issues.apache.org/jira/browse/SOLR-9908
             Project: Solr
          Issue Type: Improvement
      Security Level: Public (Default Security Level. Issues are Public)
            Reporter: Mikhail Khludnev


Right now if DIH is invoked in SolrCloud it feeds docs one by one synchronously via {{DistributedUpdateProcessor}}.  
It's proposed to create {{DIHWriter}} implementation which will stream docs with {{SolrCloudClient}}. I expect per-shard parallelism and even more with {{CloudSolrClient.setParallelUpdates(true)}}.
What's your feeling about it?
