Instead, you deploy the Cassandra message store on multiple nodes in a data center.In Cassandra, the term data center is a grouping of nodes, configured together for replication purposes. Some of the features of Cassandra architecture are as follows: Cassandra is designed such that it has no master or slave nodes. This, in turn, means that all nodes in a cluster are treated equally, and a majority of nodes can be used to achieve quorum. We would like to show you a description here but the site won’t allow us.
