Before creating a Redis Cloud database, you need to create an account and create a subscription.

To create a database in your Redis Cloud subscription:

  1. Sign in to the Redis Cloud console.

  2. If you have more than one subscription, select the target subscription from the list. This displays the Databases tab for the selected subscription.

    The Databases tab summarizes databases created for a given subscription.
  3. Select the New database button.

    The New Database button creates a new database for your subscription.

This displays the New database screen, which varies according to your subscription plan.

Use the New Database screen to create a new database for your subscription.

The New database screen is divided into sections, each dedicated to a specific category of settings. Note that not every section or setting is available to every subscription plan.

When you’ve configured your new database, use the Activate database button to create and activate it.

Use the Activate database button to create and activate your database.

General section

The General section defines basic properties about your database.

The available settings vary according to your subscription plan:

Setting name Description
Subscription Read-only description of your subscription plan, including cloud provider and region
Active-Active Redis Checked when the subscription supports Active-Active databases (Flexible or Annual subscriptions only)
Auto Tiering Checked when the subscription supports Auto Tiering (Flexible or Annual subscriptions only)
Database name A name for your database (required)
Database port Automatically or manually assigns a database port (range: 10000-19999) (Flexible or Annual subscriptions only)
Type Controls advanced database capabilities and protocol. Supported values include Redis Stack (available only for Fixed and Free), Redis (default for Flexible and Annual subscriptions), and Memcached
Advanced capabilities Extend core Redis functionality using advanced capabilities. Redis Cloud supports selected advanced capabilities; for details, see Redis Enterprise and Redis Stack feature compatibility
Supported Protocol(s) Choose between RESP2 and RESP3 (Redis 7.2 only). See Redis serialization protocol for details

Database port

All subscriptions automatically assign a database port by default.

Flexible (and Annual) subscriptions let you choose between two options:

  • Auto assign automatically assigns a port number during database creation.
  • Manually assign lets you enter a custom port number between 10000 and 19999. You cannot assign a port that is reserved or already in use.

Advanced capabilities

Advanced capabilities extend Redis database functionality by adding new data types and options.

Available options depend on your subscription and your database Type.

Fixed (and Free) advanced capability options

Fixed and Free subscriptions support Redis Stack, which enables the most frequently used capabilities.

For Fixed and Free subscriptions, the Type setting in the General section includes an option for Redis Stack.

When the database Type is set to Redis Stack, the Advanced capabilities section of the database details page displays the advanced capabilities included with the database and their versions.

For Fixed and Free subscriptions, the Database details page lists the capabilities and versions added by Redis Stack.

Redis Cloud is updated on a regular basis, which includes the advanced capabilities supported by the service. Versions displayed by the admin console may vary from those shown above. For the latest details of any capability, see Redis Stack and Redis Enterprise.

Redis Stack is available only for Fixed and Free subscriptions.

Flexible and Annual advanced capability options

Flexible and Annual subscriptions let you choose advanced capabilities for each database.

For Flexible and Annual subscriptions, you can select the capabilites included in your database.

You can select more than one advanced capability for a database, though there are limits:

  • The following advanced capabilities can be combined in Flexible and Annual subscriptions:

    • Search and query
    • JSON
    • Time series
    • Probabilistic
  • Graph cannot be combined with other capabilities.

  • JSON is the only capability supported for Active-Active subscriptions.

You don’t have to combine capabilities. To remove a selected capability, either clear the checkbox in the menu or select its Delete icon.

To remove a selected capability, clear the checkbox in the menu.   You can also use the delete icon to remove a capability.

To learn more, see Redis Stack and Redis Stack and Redis Enterprise.

Scalability section

The Scalability section lets you manage the maximum size, throughput, and hashing policy for a database.

Use the Scalability section to control the size, throughput, and hashing policy for a database.

The Scalability section is available only for Flexible and Annual plans.

Setting name Description
Memory limit Maximum size (in GB) for your database.
Throughput Defines throughput in terms of maximum operations per second for the database

Databases with search and query enabled use the number of shards to determine throughput. To determine how many shards you need for your database, use the sizing calculator.
Hashing policy Defines the hashing policy.
OSS Cluster API Enables the OSS Cluster API for a database

When this option is enabled, you cannot define a custom hashing policy.

To learn more about these settings and when to use them, see Database clustering.

Memory limit

Memory limit represents the maximum amount of memory for the database, which includes data values, keys, module data, and overhead for specific features. High availability features, such as replication and Active-Active, dramatically increase memory consumption.

Here are some general guidelines:

  • Memory limit represents an upper limit. You cannot store more data than the memory limit. Depending on your other selections, available memory for data may be much less than expected.

  • Replication doubles memory consumption; that is, 512MB of data requires at least 1GB of memory limit when replication is enabled.

  • Active-Active also doubles memory consumption and the effect is cumulative with replication’s impact. Since Active-Active requires replication to be turned on, the memory limit impact can be as large as four times (4x) the original data size.

  • Advanced capabilities also consume memory.

Memory limits in Redis Cloud are subject to the same considerations as Redis Enterprise Software; to learn more, see Database memory limits

OSS Cluster API

Redis OSS Cluster API reduces access times and latency with near-linear scalability. The Redis OSS Cluster API provides a simple mechanism for Redis clients to know the cluster topology.

Clients must first connect to the master node to get the cluster topology, and then they connect directly to the Redis proxy on each node that hosts a master shard.

Note:
You must use a client that supports the OSS cluster API to connect to a database that has the OSS cluster API enabled.

Review Redis OSS Cluster API architecture to determine if you should enable this feature for your database.

Durability section

The Durability section helps you keep your database (and your data) available when problems occur.

Use the Durability settings to keep your database (and data) available when problems occur.
Setting name Description
High availability Replicates your data across multiple nodes, as allowed by your subscription plan
Data persistence Defines whether (and how) data is saved to disk; available options depend on your plan type
Data eviction policy Configures which policy is applied when your database reaches its memory limit
Remote backup (paid Fixed, Flexible, or Annual subscriptions only) When enabled, identifies a location and interval for data backups
Active-Passive Redis (Flexible or Annual subscriptions only) When enabled, identifies a path to the linked database. See Migrate data for more information.

Tags section

The Tags section lets you add tags to the database.

Use the Tag settings to add tags to the database.

Here, you can:

  • Select Add tag to add a tag.

    The Add tag button. The New tag fields.

    You can select the tag’s Key and Value from the suggestions, or you can enter your own.

    A valid tag must follow these guidelines:

    • Tag keys must be between 2 and 64 characters long, and values must be at least 2 characters long.
    • Tags can only have lowercase letters, numbers, spaces, and these special characters: -, _, ., +, @, and :.
  • Select the Key or Value field of an existing tag and enter new text to edit it.

  • Select Delete next to a tag to delete it.

    Delete button.

Security section

The Security section helps you control access to your database.

Use the Security settings to control access to your database.
Setting name Description
Default user When enabled, permits access using a simple password
Redis password Password assigned to the database when created
CIDR allow list (paid Fixed, Flexible, or Annual subscriptions only) Allow list of IP addresses/security groups permitted to access the database
Transport layer security (TLS) (Flexible or Annual subscriptions only) Enables transport layer security (TLS) encryption for database access

Alerts section

The Alerts section defines notification emails sent to your account and the conditions that trigger them.

The Alerts section defines the notification emails and their triggering conditions.

The available alerts vary according to the subscription type.

Setting name Description
