In the Repository tree view, the NoSQL Connections node in the Metadata folder groups the metadata of the connections to NoSQL databases such as Cassandra, MongoDB, and Neo4j. It allows you to centralize the connection properties you set and then to reuse them in your Job designs that involve NoSQL database components - Cassandra, MongoDB, and Neo4j components.
Click Metadata in the Repository tree view to expand the relevant folder. Each of the connection nodes will gather the various connections and schemas you have set up. Among these connection nodes is the NoSQL Connections node.
The following sections explain in detail how to use the NoSQL Connections node to set up:
a Cassandra connection,
a MongoDB connection, and
a Neo4j connection.
