Create Presto-Connected Visualizations in Klipfolio

Klipfolio is an online dashboard platform designed to create real-time business dashboards, whether for your team or clients. When combined with CData Connect Cloud, you gain immediate cloud-to-cloud access to Presto data to create visualizations, reports, and more. This article provides step-by-step instructions on connecting to Presto within Connect Cloud and creating visualizations using Presto data in Klipfolio.

CData Connect Cloud offers a direct cloud-to-cloud interface for Presto, enabling you to construct reports from real-time Presto data data within Klipfolio—without the need for data replication to a database natively supported by Klipfolio. While building visualizations, Klipfolio generates SQL queries to fetch data. With optimized data processing capabilities out of the box, CData Connect Cloud efficiently directs all supported SQL operations (such as filters, JOINs, etc.) directly to Presto, harnessing server-side processing to swiftly retrieve the requested Presto data data.

Getting Started

---

Configure Presto Connectivity for Klipfolio

Connectivity to Presto from Klipfolio is made possible through CData Connect Cloud. To work with Presto data from Klipfolio, we start by creating and configuring a Presto connection.

1. Log into Connect Cloud, click Sources, and then click Add Connection

2. Select "Presto" from the Add Connection panel

3. 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.
   
4. Click Create & Test
5. Navigate to the Permissions tab in the Add Presto Connection page and update the User-based permissions.

Add a Personal Access Token

When connecting to Connect Cloud through the REST API, the OData API, or the Virtual SQL Server, a Personal Access Token (PAT) is used to authenticate the connection to Connect Cloud. It is best practice to create a separate PAT for each service to maintain granularity of access.

1. Click on the Gear icon () at the top right of the Connect Cloud app to open the settings page.
2. On the Settings page, go to the Access Tokens section and click Create PAT.
3. Give the PAT a name and click Create.
4. The personal access token is only visible at creation, so be sure to copy it and store it securely for future use.

With the connection configured and a PAT generated, you are ready to connect to Presto data from Klipfolio.

Connect to Presto from Klipfolio

The steps below outline connecting to CData Connect Cloud from Klipfolio to create a new Presto data source.

1. Open Klipfolio
2. Click in Data Sources to add a new data source
3. Search for and select MSSQL as the Service
4. Click "Create a custom MSSQL data source"
5. Configure the data source by setting the MSSQL connection properties:
   • Host: tds.cdata.com
   • Port: 14333
   • Database: your database (e.g., Presto1)
   • Driver: MS SQL
   • Username: a Connect Cloud user (e.g. [email protected])
   • Password: the above user's PAT
   • SQL Query: any query to retrieve data (e.g. SELECT * FROM Customer )
   • Select the checkbox to "Include column headers"
   • Select the checkbox to "Use SSL/TLS"
   
6. Click "Get data" to preview the Presto data before building a data model.

Build a Data Model

After retrieving the data, click the checkbox to "Model your data" and click "Continue." In the new window, configure your data model.

1. Confirm that the model includes all columns you wish to work with
2. Name your model
3. (optional) Set the Description
4. Set "Header in row" to 1
5. Click the toggle to "Exclude data before row" and set the value to 2
6. Click "Save and Exit"

Create a Metric

With the data modeled, we are ready to create a Metric (or visualization) of the data to be used in the Klipfolio platform for dashboards, reporting, and more.

1. Click "Create metrics"
2. Select a Data source
3. Select a Metric value and default aggregation
4. Select Segmentation(s)
5. Select a Date & time
6. Select a Data shape
7. Configure the Display settings
8. Click Save
9. Navigate to your Metric and further configure the visualization

SQL Access to Presto Data from Cloud Applications

Now you have a Metric built from live Presto data. You can add it to a new dashboard, share, and more. Easily create more data sources and new visualizations, produce reports, and more — all without replicating Presto data.
