Please have a look at this post https://support.lucidworks.com/hc/en-us/articles/201298317-What-is-SolrCloud-And-how-does-it-compare-to-master-slave-
We dont use Master slave architecture, however we use solr cloud and standalone solr for our documents. Indexing is a bit slow in cloud when compared to Standalone. This is because of replication I think. However you will get a faster query response. Solr Cloud also requires a slightly elaborate setup with Zookeepers compared to master/slave or standalone. However, once Solr cloud is setup, it runs very smoothly and you dont have to worry about the performance / high availability. Please check the post, a detailed analysis and comparison between the two has been given. -Rahul On Mon, Jan 11, 2016 at 4:58 PM, Gian Maria Ricci - aka Alkampfer < alkamp...@nablasoft.com> wrote: > Hi guys, > > > > a customer need a comprehensive list of all pro and cons of using standard > Master Slave replica VS using Solr Cloud.
