CData Connect



Use CData Connect Cloud to create a virtual MySQL Database for Redis data and build visualizations and dashbaords from Redis data in Redash.

Redash lets you connect and query your data sources, build dashboards to visualize data and share them with your company. When paired with CData Connect Cloud, you get instant, cloud-to-cloud access to Redis data for visualizations, dashboards, and more. This article shows how to create a virtual database for Redis and build visualizations from Redis data in Redash.

CData Connect Cloud provides a pure MySQL, cloud-to-cloud interface for Redis, allowing you to easily build visualizations from Redis data in Redash. As you build visualizations, Redash generates SQL queries to gather data. Using optimized data processing out of the box, CData Connect Cloud pushes all supported SQL operations (filters, JOINs, etc) directly to Redis, leveraging server-side processing to quickly return Redis data.

Create a Virtual MySQL Database for Redis Data

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

  1. Log into Connect Cloud and click Databases.
  2. Select "Redis" from Available Data Sources.
  3. Enter the necessary authentication properties to connect to Redis.

    Set the following connection properties to connect to a Redis instance:

    • Server: Set this to the name or address of the server your Redis instance is running on. You can specify the port in Port.
    • Password: Set this to the password used to authenticate with a password-protected Redis instance , using the Redis AUTH command.

    Set UseSSL to negotiate SSL/TLS encryption when you connect.

  4. Click Test Database.
  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 build visualizations in Tableau Online.

Visualize Redis Data in Tableau Online

The steps below outline creating a new data source in Redash based on the virtual Redis database in Connect Cloud and building a simple visualization from the data.

Create a New Data Source

  1. Log into Redash, click on your profile and click "Data Sources"
  2. Click the " New Data Source" button
  3. Select "MySQL (Amazon RDS)" as the Data Source Type (CData Connect uses SSL, which the standard MySQL connection in Redash does not support)
  4. On the configuration tab, set the following properties:
    • Name: Name the data source (e.g. Redis (CData Connect))
    • Host: The full URL to your CData Connect instance (e.g. https://myinstance.cdatacloud.net)
    • Port: The port of the CData Connect MySQL endpoint (e.g. 3306)
    • User: A CData Connect user
    • Password: The password for the above user
    • Database name: The name of the virtual database for Redis (e.g. Redis1)
    • Click the checkbox to Use SSQL
  5. Click Create
  6. Click the "Test Connection" button to ensure you have configured the connection properly

With the new Data Source created, we are ready to visualize our Redis data.

Create a Redis Data Visualization

  1. Click Create -> New Query
  2. Select the newly created Data Source (you can explore the data structure in the New Query wizard)
  3. Write a SQL statement to retrieve the data, for example:
    SELECT City, CompanyName FROM Customers
  4. Click the "Execute" button to load Redis data into Redash via CData Connect
  5. Use the Visualization Editor to create and analyze graphs from Redis data
  6. You can schedule the query to refresh and update the visualization periodically

SQL Access to Redis Data from Cloud Applications

At this point, you have a direct, cloud-to-cloud connection to Redis data from Redash. You can create new visualizations, build dashboards, and more. For more information on gaining SQL access to data from more than 100 SaaS, Big Data, and NoSQL sources from cloud applications like Redash, refer to our Connect Cloud page.
