data domain cluster

A set of Dgraph processes that together handle requests for a given data domain.

One of these Dgraph processes is identified as the leader node and is responsible for handling all write operations (updates, configuration changes), while the remaining Dgraph processes serve as read-only follower nodes. All Dgraph nodes in a given data domain cluster utilize the same index residing on shared storage. Each data domain cluster node is hosted on a separate Endeca Server node.

The Dgraph process of the Oracle Endeca Server is the main computational module that provides the features of the Endeca Server, such as search, refinement computation, and guided navigation.
