Redis Management

Redis is a high-performance, non-relational key-value database. It stores data in memory, which enables extremely fast query processing. Unlike relational databases, Redis does not use traditional databases and tables; instead, data is organized into keyspaces, and values can have different structures and types, such as strings, lists, sets, and hash tables.

Redis is commonly used for:

• Data caching
• Session storage
• Queue management
• Message passing between services

When creating a cluster, you can choose the Redis version: 7 or 8.1.

Users and Privileges

In your control panel, you can manage PostgreSQL users and their privileges.

Creating Users

1. Go to the Databases section and click on the cluster.
2. Open the Users tab and click Add.

3. Set the username and password:
   • Username: 3–64 characters. Letters, numbers, and special characters are allowed.
   • Password: 8–30 characters. Letters, numbers, and special characters are allowed.
4. (Optional) Configure the user’s privileges. You can also leave the default parameters and change them later at any time.
5. Click Create.

Modifying Privileges

To update the privileges of an existing user:

1. Go to the Databases section and click on the cluster.
2. Open the Users tab.
3. Click the three dots next to the user.
4. Select Privileges.

5. Choose the required privileges. You can grant access to a specific database or grant the same privileges for all databases by enabling Identical for all databases in the top right.

Available Privileges

Changing User Password

You can change the user password:

1. Go to the Database section and click on the cluster.
2. Go to the Users tab.
3. Click the three dots next to the user.
4. Select Change password.

5. Enter a new value and save changes.

Database Parameters

You can change database settings to optimize its performance. 

By default, the database is created with the parameters that are suitable for most tasks and will ensure the performance of the selected configuration. However, if your project requires specific settings, you can change them as you wish. 

Be careful and change parameters only if you are sure of their purpose. Incorrect configuration can negatively affect the operation of the database and its performance.

Changing Parameters

1. Go to the Databases section and click on the cluster.
2. Go to the Configuration tab.
3. Click Modify parameters next to Database parameters.

4. Adjust the parameters. To read more about each parameter, click Open description next to it.

5. Click Apply at the bottom of the page.

Parameters List

Connecting to the Database

To work with a Redis cluster in DBaaS, install the redis-cli utility. It is included in the Redis package and can be installed via package managers:

• Ubuntu/Debian

sudo apt install redis-tools

• macOS

brew install redis

• Arch Linux

sudo pacman -S redis

• CentOS/RHEL

sudo yum install redis

After installation, check the client version:

redis-cli -v

There are two ways to connect to a Redis cluster:

• via public IP;
• via private IP.

You can copy the connection command from:

• the Dashboard tab:

• the Connection tab:

Creating a Dump

To export Redis data, use the redis-dump-go utility, available for different architectures. Download the binary for your architecture from the official repository.

To create a dump, run:

REDISDUMPGO_AUTH='password' ./redis-dump-go -host <cluster-ip> -port 6379 -user default > redis-dump.txt

Here, REDISDUMPGO_AUTH is the password for cluster access.

Importing a Dump

To import data, use redis-cli in --pipe mode, which supports loading large datasets:

redis-cli -h <cluster-ip> -p 6379 --user default --pass 'password' --pipe < redis-dump.txt
