::::{note}
This setting is used by the [shrink](/reference/shrink.md) action.
::::
This setting must be `true` or `false`.
Setting this to `false` will result in the [shrink](/reference/shrink.md) action only checking that the index being shrunk has finished being relocated, and not continue to wait for the cluster to fully rebalance all shards.
The default value for this setting is `false`.
