rpk topic alter-config

Set, delete, add, and remove key/value configs for a topic.

This command allows you to incrementally alter the configuration for multiple topics at a time.

Incremental altering supports four operations:

  1. Setting a key=value pair

  2. Deleting a key’s value

  3. Appending a new value to a list-of-values key

  4. Subtracting (removing) an existing value from a list-of-values key

The --dry option will validate whether the requested configuration change is valid, but does not apply it.
