Alexandre Rafalovitch commented on SOLR-9908:
---------------------------------------------

Just to clarify, are you saying that the original assumption in the case is wrong and the implementation in 7.0 (and 6.x?) is already parallelized?

> 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?
