follower node

A node in a cluster of MDEX Engine nodes responsible for processing queries. The follower node does not update the index although it has read-only access to its latest copy. Each cluster can have more than one follower nodes. In a single-node cluster, a leader node is also a follower node. Each follower node must have a unique name across the cluster. All nodes (including follower nodes) must have write access to a shared file system.
