| Config name | Type | Default | Valid values | Importance | Dynamic update mode | Description |
|---|---|---|---|---|---|---|
| reassignment.max.concurrent.leader.movements | int | Int.MAX | [1,...] | medium | cluster-wide | This new configuration would tell how many replicas of a single partition can be moved at once. |
| reassignment.max.concurrent.partition.movements | int | Int.MAX | [1,...] | medium | cluster-wide | This configuration puts an upper limit on how many partition reassignments can be run concurrently. To calculate the sum of concurrent movements one can multiply this config by |
| reassignment.max.concurrent.replica.movements | int | Int.MAX | [1,...] | medium | clusterper-widepartition | This one puts an upper limit on concurrent leader replica movements. It is useful to reduce the controller burden on big reassignments. |

We will add a field to the `ListPartitionReassignmentsResponse` protocol (added by KIP-455) that will extend the response with the current reassignment batch. We don't need to change the protocol version as long as the two KIPs are released together in the same version'll increment the API version of this protocol with this change.
