Create Kafka-Connected Visualizations in Klipfolio

Klipfolio is an online dashboard platform for building real-time business dashboards for your team or your clients. When paired with CData Connect Server, you get instant access to Kafka data for visualizations, reports, and more. This article shows how to create a virtual database for Kafka in Connect Server and build visualizations from Kafka data in Klipfolio.

CData Connect Server provides a pure SQL Server interface for Kafka, allowing you to easily build reports from live Kafka data in Klipfolio — without replicating the data to a natively supported database. As you build visualizations, Klipfolio generates SQL queries to gather data. Using optimized data processing out of the box, CData Connect Server pushes all supported SQL operations (filters, JOINs, etc) directly to Kafka, leveraging server-side processing to quickly return the requested Kafka data.

Create a Virtual SQL Server Database for Kafka Data

CData Connect Server uses a straightforward, point-and-click interface to connect to data sources and generate APIs.

1. Login to Connect Server and click Connections.
2. Select "Kafka" from Available Data Sources.
3. Enter the necessary authentication properties to connect to Kafka.

   Set BootstrapServers and the Topic properties to specify the address of your Apache Kafka server, as well as the topic you would like to interact with.

   Authorization Mechanisms

   • SASL Plain: The User and Password properties should be specified. AuthScheme should be set to 'Plain'.
   • SASL SSL: The User and Password properties should be specified. AuthScheme should be set to 'Scram'. UseSSL should be set to true.
   • SSL: The SSLCert and SSLCertPassword properties should be specified. UseSSL should be set to true.
   • Kerberos: The User and Password properties should be specified. AuthScheme should be set to 'Kerberos'.

   You may be required to trust the server certificate. In such cases, specify the TrustStorePath and the TrustStorePassword if necessary.

4. Click Save Changes
5. Click Privileges -> Add and add the new user (or an existing user) with the appropriate permissions.

With the virtual database created, you are ready to connect to Kafka data from Klipfolio.

Connect to Kafka in Klipfolio

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

1. Open Klipfolio
2. Click in Data Feeds on the left panel to add a new data source.
3. Search for and select MS SQL as the Service.
4. Click "Create a custom MSSQL data source"
5. Configure the data source by setting the SQL Server connection properties:
   • Host: your instance (e.g., CONNECT_SERVER_URL)
   • Port: 1433
   • Database: your database (e.g., ApacheKafka1)
   • Driver: MS SQL
   • Username: your Connect Server username
   • Password: your Connect Server password
   • SQL Query: any query to retrieve data (e.g., SELECT * FROM SampleTable_1)
   • Select the checkbox to "Include column headers"
6. Click "Get data" to preview the Kafka data before building a data model.

Build a Data Model

After retrieving the data, 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 data feed"

Create a Klip

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

1. Click "Add Metric"
2. Select a measure, placed on the y-axis, to track.
3. Select up to five dimensions/columns, for the x-axis, that you wish to visualize.
4. Click "Save metric"

SQL Access to Kafka Data from Applications

Now you have a Klip built from live Kafka 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 Kafka data.
