# Suspend & Resume Clusters

Clusters can be suspended when they are not in use to save infrastructure costs and resumed when they are needed again.

{% hint style="info" %}
In some cases, not all executors will come online immediately when a cluster is resumed due to infrastructure availability limitations. The remaining executors will become active as soon as resources are available.

Users will still be able to run queries using a partially active cluster.
{% endhint %}

## Suspend Clusters

Clusters can be suspended in two ways:

* [Manually via the Cluster dashboard](#suspend-clusters-manually)
* [Automatically using Auto Suspension](#set-up-auto-suspension)

### Suspend Clusters Manually

1. Navigate to **Clusters**
2. Click the pause button next to the cluster to be suspended.

Cluster Suspension Process
{% endembed %}

### Set up Auto Suspension

If Auto Suspension is configured in a cluster it will be suspended when it is not used for a defined period of time.

Refer to the [Auto Suspension](/product-documentation/clusters/auto-suspension.md) documentation for instructions.

## Resume Clusters

Clusters can be resumed in two ways:

* [Manually via the Cluster dashboard](#resume-clusters-manually)
* [Via the Query Editor](#resume-clusters-via-the-query-editor)

### Resume Clusters Manually

* Navigate to **Clusters**
* Click the play button next to the cluster to be resumed.

Cluster Resume Process
{% endembed %}

### Resume Clusters via the Query Editor

If a user tries to run a query using a suspended cluster via the Query Editor, they will be prompted for consent to resume the cluster.

{% hint style="info" %}
The "Refresh List" button will update the statuses of the clusters.
{% endhint %}
