Connect and Visualize Live Kintone Data in Databricks Lakehouse Federation with CData Connect Cloud

Databricks Lakehouse Federation enables organizations to query and integrate data from multiple sources without requiring data movement. It allows federated queries across databases, data warehouses, and lakehouses, providing a unified interface for data analysis and management within Databricks. When combined with CData Connect Cloud, it enables seamless access to Kintone data for data virtualization, while also supporting data lineage and fine-grained access control.

This article explains how to use CData Connect Cloud to establish a live connection to Kintone and how to access live Kintone data from the Databricks platform.

CData Connect Cloud offers a seamless SQL Server, cloud-to-cloud interface for Kintone, enabling you to effortlessly create dashboards and visualizations using live Kintone data in Databricks. While building visualizations, Databricks requires SQL queries to retrieve the necessary data. With built-in optimized data processing, CData Connect Cloud pushes all supported SQL operations (such as filters and JOINs) directly to Kintone, utilizing server-side processing for fast and efficient data retrieval of Kintone data.

Configure Kintone connectivity for Databricks in CData Connect Cloud

To work with Kintone data in Databricks - Lakehouse Federation, you need to connect to Kintone from Connect Cloud and provide user access to the connection.

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

2. Select "Kintone" from the Add Connection panel

3. Enter the necessary authentication properties to connect to Kintone.

   In addition to the authentication values, set the following parameters to connect to and retrieve data from Kintone:

   • Url: The URL of your account.
   • GuestSpaceId: Optional. Set this when using a guest space.

   Authenticating with Kintone

   Kintone supports the following authentication methods.

   Using Password Authentication

   You must set the following to authenticate:

   • User: The username of your account.
   • Password: The password of your account.

   Using Basic Authentication

   If the basic authentication security feature is set on the domain, supply the additional login credentials with BasicAuthUser and BasicAuthPassword. Basic authentication requires these credentials in addition to User and Password.

   Using Client SSL

   Instead of basic authentication, you can specify a client certificate to authenticate. Set SSLClientCert, SSLClientCertType, SSLClientCertSubject, and SSLClientCertPassword. Additionally, set User and Password to your login credentials.

   
4. Click Create & Test
5. Navigate to the Permissions tab in the Add Kintone 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 Kintone data from Databricks.
