rpk cluster partitions move

Move partition replicas across nodes / cores.

This command changes replica assignments for given partitions. By default, it assumes the kafka namespace, but you can specify an internal namespace using the {namespace}/ prefix.

To move replicas, use the following syntax:

Here, the command assigns new replicas for partition 0 to brokers [1, 2, 3] and for partition 1 to brokers [2, 3, 4] for the topic foo.

You can also specify the core id with -{core_id} where the new replicas should be placed:

Here all new replicas [1, 2, 3] will be assigned on core 0 on the nodes.

The command does not change a core assignment unless it is explicitly specified. When a core is not specified for a new node, the command randomly picks a core and assign a replica on the core.

Topic arguments are optional. For more control, you can specify the topic name in the “--partition” flag:
