What's new in Klaw 2.0.0

Redesigned request screens with React UI

With the switch to React, this release features a redesign of the following user interfaces:

  • Topic request: Users can now submit topic requests using the new UI.
  • Subscription request (Producer/Consumer): Users can now submit ACL requests for both producers and consumers using the new UI.
  • Schema request: Users can now submit schema requests using the new UI.


To preview the new Klaw user interface, open the file on the Klaw core module, and set the value of the following property to true:

Enable new Klaw user

interface klaw.coral.enabled=true


We are taking an incremental, feedback-driven approach in rolling out the new Klaw interfaces. By providing the feature flag to preview user interfaces, we would like you to share your valuable feedback.

Schema promotion

Users can now promote their schemas from lower to higher environments. They can select a specific version of the schema and submit a request for approval. Once the request is approved, the schema will be created in the target environment. Additionally, there is now an option to force-register the schema in case of any compatibility issues during registration.

For more information, see Schema promotion.

Authorization from OAuth2 provider/Active Directory

With this release, users can now be authorized through an OAuth2 Provider or Active Directory. Roles for users can be defined in the provider, such as grants in Azure Active Directory, and Klaw will validate and assign these roles to users during the sign-up process.

For more information, see Authorization.

To enable the authorization feature, set the below property to value true in the file: : = true
