# Index rollup settings
We don't recommend changing these settings; the defaults should work well for most use cases.
All settings are available using the OpenSearch `_cluster/settings` operation. None require a restart, and all can be marked `persistent` or `transient`.
Setting | Default | Description
:--- | :--- | :---
`plugins.rollup.search.backoff_millis` | 1000 milliseconds | The backoff time between retries for failed rollup jobs.
`plugins.rollup.search.backoff_count` | 5 | How many retries the plugin should attempt for failed rollup jobs.
`plugins.rollup.search.search_all_jobs` | false | Whether OpenSearch should return all jobs that match all specified search terms. If disabled, OpenSearch returns just one, as opposed to all, of the jobs that matches the search terms.
`plugins.rollup.dashboards.enabled` | true | Whether rollups are enabled in OpenSearch Dashboards.
`plugins.rollup.enabled` | true | Whether the rollup plugin is enabled.
`plugins.ingest.backoff_millis` | 1000 milliseconds | The backoff time between data ingestions for rollup jobs.
`plugins.ingest.backoff_count` | 5 | How many retries the plugin should attempt for failed ingestions.

:--- | :--- | :--- :--- | :--- | :---
`plugins.index_state_management.enabled` | True | Specifies whether ISM is enabled or not. `plugins.index_state_management.enabled` | True | Specifies whether ISM is enabled or not.
`plugins.index_state_management.job_interval` | 5 minutes | The interval at which the managed index jobs are run. `plugins.index_state_management.job_interval` | 5 minutes | The interval at which the managed index jobs are run.
`plugins.index_state_management.jitter` | 0.6 | A randomized delay that is added to a job's base run time to prevent a surge of activity from all indices at the same time. A value of 0.6 means a delay of 0-60% of a job interval is added to the base interval. For example, if you have a base interval time of 30 minutes, a value of 0.6 means an amount anywhere between 0 to 18 minutes gets added to your job interval. Maximum is 1, which means an additional interval time of 100%. This maximum cannot exceed `plugins.jobscheduler.jitter_limit`, which also has a default of 0.6. For example, if `plugins.index_state_management.jitter` is set to 0.8, ISM uses `plugins.jobscheduler.jitter_limit` of 0.6 instead.
`plugins.index_state_management.coordinator.sweep_period` | 10 minutes | How often the routine background sweep is run. `plugins.index_state_management.coordinator.sweep_period` | 10 minutes | How often the routine background sweep is run.
`plugins.index_state_management.coordinator.backoff_millis` | 50 milliseconds | The backoff time between retries for failures in the `ManagedIndexCoordinator` (such as when we update managed indices). `plugins.index_state_management.coordinator.backoff_millis` | 50 milliseconds | The backoff time between retries for failures in the `ManagedIndexCoordinator` (such as when we update managed indices).
`plugins.index_state_management.coordinator.backoff_count` | 2 | The count of retries for failures in the `ManagedIndexCoordinator`. `plugins.index_state_management.coordinator.backoff_count` | 2 | The count of retries for failures in the `ManagedIndexCoordinator`.
