Tableau Connector for Couchbase

Build 21.0.7930

Configuring a Connection

The connector comes with a connection builder which allows you to build and test your connection settings outside of Tableau. It also allows you to create a connection string, which can be used to provide options not listed in the connection dialog in Tableau.

Configuring a Connection Builder

There are two ways to access the connection builder:

  • On Windows, there will be a shortcut called Connection Builder in the start menu, under the CData Couchbase Tableau Data Connector folder.
  • The connection builder can also be started by going to the driver install directory and running the .jar file in the lib directory.

In the connection builder, you can set values for connection properties and click the Test Connection button to validate that they work. You can also use the Copy to Clipboard button to save the connection string for use with Tableau.

Connecting to Couchbase

To connect to data, set the Server property to the hostname or IP address of the Couchbase server(s) you are authenticating to. If your Couchbase server is configured to use SSL, you can enable it either by using an https URL for Server (like 'https://couchbase.server'), or by setting the UseSSL property to True.

Couchbase Analytics

By default, the connector connects to the N1QL Query service. In order to connect to the Couchbase Analytics service, you will also need to set the CouchbaseService property to Analytics.

Couchbase Cloud

A few special settings are required to connect to Couchbase Cloud:

  • Set the AuthScheme to Basic
  • Set the Server option to the domain listed in the Couchbase Cloud console.
  • Enable the UseSSL option.
  • Set the ConnectionMode to Cloud
  • Set the DNSServer option to a DNS server. In most cases this should be a public DNS service like or
  • Set the SSLServerCert option to * to trust the Couchbase server certificate. You can also provide the certificate using that option or your trust store if you want the connector to validate it.

Authenticating with Couchbase

The connector supports several forms of authentication depending upon how your Couchbase Server is configured. Couchbase Cloud only accepts Standard Authentication, while Couchbase Server accepts all forms.

Authenticating with Standard Authentication

To authenticate with standard authentication, set the following:

  • AuthScheme: Use the Basic option.
  • User: The user authenticating to Couchbase.
  • Password: The password of the user authenticating to Couchbase.

Authenticating with Client Certificates

The connector supports authenticating with client certificates when SSL is enabled. To use client certificate authentication, set the following properties.

  • AuthScheme: Required. Use the SSLCertificate option.
  • SSLClientCertType: Required. The type of client certificate set within SSLClientCert.
  • SSLClientCert: Required. The client certificate in the format given by SSLClientCertType. Usually the path to your private key file.
  • SSLClientCertPassword: Optional. The password of the client certificate if it is encrypted.
  • SSLClientCertSubject: Optional. The subject of the client certificate, by default the first certificate found in the store. This is required if more than one certificate is available in the certificate store.

Authenticating with a Credentials File

You can also authenticate using using a credentials file containing multiple logins. This is included for legacy use and is not recommended when connecting to a Couchbase Server that supports role-based authentication.

  • AuthScheme: Use the CredentialsFile option.
  • CredentialsFile; The path to the credentials file. Refer to Couchbase's documentation for more information on the format of this file.

Next Step

See Getting Data for the next step, which includes authenticating to the Couchbase APIs.
