Connect to Redis Data from HeidiSQL

HeidiSQL is an open-source database administration tool that natively supports MariaDB, MySQL, SQL Server, and PostgreSQL. When paired with CData Connect Cloud, HediSQL reach extends to include access to live Redis data. This article demonstrates how to connect to Redis using Connect Cloud and query Redis data in HeidiSQL.

CData Connect Cloud provides a pure SQL Server interface for Redis, allowing you to query data from Redis without replicating the data to a natively supported database. 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 return the requested Redis data quickly.

Configure Redis Connectivity for HeidiSQL

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

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

2. Select "Redis" from the Add Connection panel

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 Create & Test
5. Navigate to the Permissions tab in the Add Redis 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 Redis data from HeidiSQL.

Connect to Redis from HeidiSQL using Connect Cloud

To establish a connection from HeidiSQL to the CData Connect Cloud Virtual SQL Server API, follow these steps.

Create a new HeidiSQL Session

1. In the Session Manager, select New in the bottom-left
2. Give the new session a descriptive name, e.g. Connect-Cloud-Redis

Configure a SQL Server Connection to Connect Cloud

1. In the session settings, set the Network type to Microsoft SQL Server (TCP/IP)
2. The Library DLL should automatically update to MSOLEDBSQL
3. Set the Hostname/IP to tds.cdata.com
4. Set the User to your CData Connect Cloud username. This is displayed in the top-right corner of the CData Connect Cloud interface. For example, [email protected]
5. Set the Password to your PAT created in Connect Cloud in the previous section.
6. Set the Port to 14333

Query Redis from HeidiSQL

1. In the database listing on the left, find your connection to Redis configured earlier.
2. Expand this connection to view individual tables or data objects present within Redis.
3. Write custom SQL queries targeting these tables, treating the data source like any SQL Server database, or visually explore each tabular data set by selecting the relevant tables
