Integrate Presto data into dashboards in TIBCO Spotfire.
OData is a major protocol enabling real-time communication among cloud-based, mobile, and other online applications. The CData Connect Server provides Presto data to OData consumers like TIBCO Spotfire. This article shows how to use the Connect Server and Spotfire's built-in support for OData to access Presto data in real time.
Configuring Connect Server
To work with live Presto data in TIBCO Spotfire, we need to connect to Presto from Connect Server, provide user access to the new virtual database, and create OData endpoints for the Presto data.
Add a Connect Server User
Create a User to connect to Presto from TIBCO Spotfire through Connect Server.
- Click Users -> Add
- Configure a User
- Click Save Changes and make note of the Authtoken for the new user
Connect to Presto from Connect Server
CData Connect Server uses a straightforward, point-and-click interface to connect to data sources and generate APIs.
- Open Connect Server and click Connections
- Select "Presto" from Available Data Sources
- Enter the necessary authentication properties to connect to Presto.
Set the Server and Port connection properties to connect, in addition to any authentication properties that may be required.
To enable TLS/SSL, set UseSSL to true.
Authenticating with LDAP
In order to authenticate with LDAP, set the following connection properties:
- AuthScheme: Set this to LDAP.
- User: The username being authenticated with in LDAP.
- Password: The password associated with the User you are authenticating against LDAP with.
Authenticating with Kerberos
In order to authenticate with KERBEROS, set the following connection properties:
- AuthScheme: Set this to KERBEROS.
- KerberosKDC: The Kerberos Key Distribution Center (KDC) service used to authenticate the user.
- KerberosRealm: The Kerberos Realm used to authenticate the user with.
- KerberosSPN: The Service Principal Name for the Kerberos Domain Controller.
- KerberosKeytabFile: The Keytab file containing your pairs of Kerberos principals and encrypted keys.
- User: The user who is authenticating to Kerberos.
- Password: The password used to authenticate to Kerberos.
- Click Save Changes
- Click Privileges -> Add and add the new user (or an existing user) with the appropriate permissions (SELECT is all that is required for Reveal).
Add Presto OData Endpoints in Connect Server
After connecting to Presto, create OData Endpoints for the desired table(s).
- Click OData -> Tables -> Add Tables
- Select the Presto database
- Select the table(s) you wish to work with and click Next
- (Optional) Edit the resource to select specific fields and more
- Save the settings
(Optional) Configure Cross-Origin Resource Sharing (CORS)
When accessing and connecting to multiple domains from an application such as Ajax, there is a possibility of violating the limitations of cross-site scripting. In that case, configure the CORS settings in OData -> Settings.
- Enable cross-origin resource sharing (CORS): ON
- Allow all domains without '*': ON
- Access-Control-Allow-Methods: GET, PUT, POST, OPTIONS
- Access-Control-Allow-Headers: Authorization
Save the changes to the settings.
Create Data Visualizations on External Presto Data
- Open Spotfire and click Data -> Add data...
- Then, click "Connect to" -> OData -> New Connection. In the OData Connection dialog, enter the following information:
- Service URL: Enter the Connect Server's OData endpoint. For example:
http://localhost:8080/odata.rsc
- Authentication Method: Select Username and Password.
- Username: Enter the username of a Connect Server user. You can create API users on the Security tab of the administration console.
- Password: Enter the authtoken of a Connect Server user.
- Service URL: Enter the Connect Server's OData endpoint. For example:
- Select the tables and columns you want to add to the dashboard. This example uses Customer.
-
If you want to work with the live data, click the Keep Data Table External option. This option enables your dashboards to reflect changes to the data in real time.
If you want to load the data into memory and process the data locally, click the Import Data Table option. This option is better for offline use or if a slow network connection is making your dashboard less interactive.
- After you have selected a table, Spotfire uses the data to detect number, time, and other categories. You are now on your way to creating new visualizations for analytics, reporting, and more.
