In Kafka, clients perform operations on resources in Kafka.
The following tables list the resource types and the operations that apply to them.
2.1. Resource types and operations
This table lists the resource types and operations enforced by the authorization filter:
| Resource type | Operations | Typical use-case |
|---|---|---|
| Topic | READ | Required for a consuming client to fetch records. |
| WRITE | Required for a producing client to produce records. | |
| CREATE | Required for an admin client to create, delete or alter topics. | |
| DELETE | ||
| ALTER | ||
| DESCRIBE | Required for an admin client to perform the describe operations that refer to topic resources. | |
| DESCRIBE_CONFIGS | Required for an admin client to perform describe config operations that refer to topic configuration. | |
| ALTER_CONFIGS | Required for an admin client to perform alter config operations that relate to topic configuration. NOTE: Other Kafka resource types will be included in a future release. |
2.2. Implied operation permissions
In the authorization model, some operations imply permission to perform other operations. This table lists the higher-level operations and the implied lower-level operations they include.
| Resource type | Operation | Implied Operation |
|---|---|---|
| Topic | READ | DESCRIBE |
| WRITE | ||
| DELETE | ||
| ALTER | ||
| ALTER_CONFIGS | DESCRIBE_CONFIG |
