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:
-
Setting a key=value pair
-
Deleting a key’s value
-
Appending a new value to a list-of-values key
-
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.
