Enabling Swarms

This menu item lets you enable Swarm clusters, ephemeral ClickHouse® clusters that are scalable pools of self-registering, stateless servers. (The Altinity blog has a discussion of swarms if you’d like to know more.)

Be aware that you enable swarms on a cluster-by-cluster basis. If you create a new cluster with the Launch Cluster wizard, you won’t be able to use swarms on the new cluster until you use this menu item. Also be aware that enabling swarms will cause a restart of your cluster.

This menu item is currently disabled by default, but please contact us and we can enable swarms for your environment.

When enabling swarms for your cluster, clicking this menu item asks you to confirm your choice:

Figure 1 - Enabling swarms for a particular cluster

When swarms are enabled, you’ll get the good news:

Figure 2 - Swarms are enabled for this cluster

Now you can create swarms using the Launch Cluster Wizard. Simply click the button, go through a simple wizard, and you’ll have a swarm cluster. See the Launch Cluster Wizard documentation for all the details.

If swarms are already enabled, you’ll see this dialog instead:
