# Redis

Redis (Remote Dictionary Server) is an open-source in-memory data structure store. Due to the nature of being fast, scalable, and highly available, Redis is a popular choice for applications that require real-time data processing, high throughput, and low latency.

## Prerequisites

* Get Redis database connection parameters from the database owner.
* Refer to IP allowlist to add IP addresses of OpenFlower to your allowlist (if needed).

## Connect to Redis data source

Follow the steps below:

1. Create a new data source in two ways. Note that this permission is restricted to workspace admins and developers.
   * Navigate to the **Data Sources** tab on [OpenFlower Homepage](https://prod-us1.openflower.org) and click **New data source**.
   * When creating a new query in the app editor, click **+ New** > **+ New data source**.
2. Select **Database** > **Redis** as the data source type.
3. Set its name and configure the parameters according to your **Connection Type**:
   * **Regular**: Host, port, database name (required); user name, password (optional)
   * **URI**: URI
4. (Optional) Click **Test connection** to check whether the new data source is successfully connected.
5. Click **Save**, and it will be saved to your data source library.
