What are RisingWave premium features?
RisingWave offers a set of premium features for enterprise and mission-critical use cases. These features are built on top of the open-source RisingWave Community Edition and provide advanced capabilities to help users maximize the benefits of their RisingWave deployments. The Community Edition will continue to be freely available under the Apache License (Version 2.0), and we remain committed to supporting the needs of our open-source community and ecosystem. RisingWave’s core functionalities and a majority of its features are, and will always be, available in the Community Edition.How to access premium features
Access to premium features depends on your RisingWave setup.Self-managed deployments
For self-managed RisingWave clusters, you need to purchase a license key to unlock premium features. The RisingWave Community Edition and the binaries with premium features share the same underlying code. The license key simply unlocks the premium capabilities.RisingWave Cloud
The availability of premium features in RisingWave Cloud depends on your subscription tier.- Pro Tier: All premium features are available out-of-the-box for users on the Pro tier.
- Basic Tier: Users on the Basic tier have access to premium connectors without any additional charges. To access all other premium features, you will need to upgrade to the Pro tier.
Available premium features
Each row below is a premium feature. On RisingWave Cloud, all features in Connectors are included on both the Basic and Pro tiers; everything else requires the Pro tier. On self-managed deployments, every premium feature requires a license key.| Category | Feature | What it does |

Set up a license key
For self-managed deployments, you need to purchase and set up a license key to access premium features. The license key, essentially a certificate, is a JSON Web Token (JWT) that encodes information such as the license tier and expiration time. The integrity of the license key is validated using asymmetric encryption.Free trial
RisingWave provides a trial of paid features for clusters with up to 4 RWUs (RisingWave Units), allowing you to evaluate these features on a small scale. With 4 RWUs, your cluster can use up to 4 CPU cores and 16 GiB of total memory. When the cluster exceeds either of these limits, the trial will be unavailable for both existing and future jobs, and you will need to acquire a license key to continue using the paid features.- For a fresh deployment, this free trial is included automatically.
- For an existing deployment upgrading to this version, you may need to refresh the license key by executing
ALTER SYSTEM SET license_key TO DEFAULT;in the SQL shell to activate the trial.
Set license key
Depending on the deployment, there are several different ways of setting license key.- RisingWave Operator (Kubernetes)
- Helm (Kubernetes)
- SQL
- Local
If you used the RisingWave Operator to deploy the RisingWave,
you could follow the steps to set the license key.
For detailed instructions of deploying RisingWave with the RisingWave Operator, please check the Deploy RisingWave on Kubernetes with Operator.
-
Prepare a secret under the same namespace as the RisingWave object, e.g.,
-
Set the following fields of the RisingWave object.
- Apply the RisingWave object to Kubernetes.
Verify license key
To check if your license key is valid and test the availability of a specific feature, run:feature_name with the name of the feature you want to test. A result of t means the feature is available; an error message indicates the feature is not available based on your license.
rw_test_paid_tier() will be deprecated in a future release. Use rw_test_feature() instead.View available features
To view all license-gated features and their availability, query therw_features system table:
Retrieve license details
To retrieve detailed license information, run:- For
rwu_limit, this specifies the number of RWUs (RisingWave Units) you can use for your cluster. Each RWU corresponds to 1 CPU core and 4 GiB of memory. With anrwu_limitof X, your cluster may use up to X CPU cores and up to (X * 4) GiB of total memory. Exceeding either limit will disable premium features. See RisingWave Unit (RWU) for more details. - For
exp, this specifies the expiry time in Unix epoch seconds. You can use theto_timestampfunction to convert the Unix epoch into a readable timestamp.
