Traditional replication behind SolrCloud

[Mingfeng Yang <mf...@wisewindow.com>]

Our application of Solr is somehow non-typical.  We constantly feed Solr
with lots of documents grabbed from internet, and NRT searching is not
required.  A typical search will return millions of result, and query
response need to be as fast as possible.

Since in SolrCloud environment, indexing request is constantly distributing
to all leaders and replicas, and I think that may impact the query
performance since the replicas are doing indexing and searching at the same
time.   I think about setting up a traditional replication behind each
shard of SolrCloud, and set the replication interval to a few minutes, to
minimize the impact of indexing on system resources.

Or is there already some way to enforce traditional type of replication in
the replicas of SolrCloud?

Thanks,
