Schema Registry Authorization
Describes authorization for Kafka Schema Registry.
In secure clusters, authorization is enabled by default.
You can enable or disable authorization for the Schema Registry in the
<schema-registry-dir>/etc/schema-registry/schema-registry.properties
file through the following option:authorization.enable=[true|false]Permissions
Permissions grant access to internal data in the Schema Registry, such as schemas, subjects, and server configurations. Read permission grants access to view data. Modify permission grants access to add, update, and remove data.
The following sections describe operations that require read and modify
access.
NOTE
To avoid any unexpected behaviours when using Schema Registry with KSQL,
Kafka Rest, Kafka Connect, or custom Java applications, both read and modify
permissions are required.REST API Operations that Require Read Access
