Connection Manager

DataStax DevCenter is compatible with DataStax Enterprise (DSE) versions up to 5.0.

The Connection Manager provides a simple and friendly way to add and manage connections to existing DataStax Enterprise clusters.

When connected, the square brackets to the right of the connection name display number-of-connected-nodes / number-of-nodes-in-hosts-list.

New connection

Add a new connection by either selecting File > New > Connection, by clicking the New connection button in the toolbar of the connection manager view, or typing ⌥⇧+⌘+N (Macintosh) / Ctrl+Alt+Shift+N (Windows, Linux).

The dialog for creating a new connection allows configuring a connection to an existing cluster by entering:

a connection name
one or more IP addresses of nodes in the cluster
the connection protocol (by default 9042)
which compression to use (none, Snappy, or LZ4)
Security configuration:
- Supply the authentication credentials, whether the cluster is using either DSE Unified Authentication or Setting up the environment for Kerberos .
- whether SSL is to be used for Node-to-node encryption using SSL.
  - The Truststore file contains the public certificates from the cluster nodes, and the Truststore password is used to access the password-protected Truststore file.
    - whether client authentication is to be used (that is, if require_client_auth is set to true in the cassandra.yaml file); supply the authentication credentials
    - The Keystore file contains the private certificate for the client, and the Keystore password is used to access the password-protected Keystore file.

DevCenter uses a whitelist policy to connect with hosts in your cluster. DevCenter establishes a connection only to the nodes that have been added in the Contact hosts list in the Connection wizard.
