SolrCloud provides fault-tolerant distributed search capabilities using Apache Solr. SolrCloud supports all types of distributed search configurations. It also has in-built load balancing capabilities that optimize effective load on all the nodes participating in SolrCloud. With the simplest configuration of all, the cloud can be set up.
Tip
A collection in Solr is a combination of one or more indexes spanning one or more cores of Apache Solr.
SolrCloud lets you create a cluster of Solr nodes, each of them running one or more collections. A collection holds one or more shards which are hosted on one or more (in case of replication) nodes.
Any updates to any nodes participating in SolrCloud can in turn sync of rest of the nodes. It uses Apache Zookeeper to bring in distributed coordination and configuration among multiple nodes. This in turn enables near real-time searching on SolrCloud due to active sync of indexes. Apache Zookeeper...
