In CDCR docs, it is written that "The SolrCloud architecture is not particularly well suited for situations = where a single SolrCloud cluster consists of nodes in separated data cluste= rs connected by an expensive pipe". But we fail to find, what latency is acceptable for SolrCloud/ZK and when w= e should start considering using CDCR (master-slave). And what would be the= issues if we install SolrCloud on problematic network? Thanks in advance, Pavel --_000_92dfddd8e4984775ac8b1ccea83b490azoomintcom_--
