 `xpack.ml.nightly_maintenance_requests_per_second`
 :   ([Dynamic](docs-content://deploy-manage/stack-settings.md#dynamic-cluster-setting)) The rate at which the nightly maintenance task deletes expired model snapshots and results. The setting is a proxy to the [`requests_per_second`](https://www.elastic.co/docs/api/doc/elasticsearch/operation/operation-delete-by-query) parameter used in the delete by query requests and controls throttling. When the {{operator-feature}} is enabled, this setting can be updated only by operator users. Valid values must be greater than `0.0` or equal to `-1.0`, where `-1.0` means a default value is used. Defaults to `-1.0`
 
+`xpack.ml.results_index_rollover_max_size`
+:   ([Dynamic](docs-content://deploy-manage/stack-settings.md#dynamic-cluster-setting)) The maximum size the anomaly detection results indices can reach before being rolled over by the nightly maintenance task. When the {{operator-feature}} is enabled, this setting can be updated only by operator users. Valid values must be greater than or equal to `-1B`. A value of `-1B` means the indices will never be rolled over. A value of `0B` means the indices will always be rolled over, regardless of size. Defaults to `50GB`.
+
 `xpack.ml.node_concurrent_job_allocations`
 :   ([Dynamic](docs-content://deploy-manage/stack-settings.md#dynamic-cluster-setting)) The maximum number of jobs that can concurrently be in the `opening` state on each node. Typically, jobs spend a small amount of time in this state before they move to `open` state. Jobs that must restore large models when they are opening spend more time in the `opening` state. When the {{operator-feature}} is enabled, this setting can be updated only by operator users. Defaults to `2`.
