```
public class TopicConfig
extends Object
```
Keys that can be used to configure a topic. These keys are useful when creating or reconfiguring a topic using the AdminClient.
The intended pattern is for broker configs to include a `log.` prefix. For example, to set the default broker cleanup policy, one would set log.cleanup.policy instead of cleanup.policy. Unfortunately, there are many cases where this pattern is not followed.
