Cluster Settings

Crunchy Bridge allows you to customize each cluster in a number of ways to suit your specific needs. The cluster settings outlined below can be freely changed without causing any downtime or service interruption.

Cluster Name setting

A cluster’s name can be changed at any time in the Cluster Settings page:

Rename Cluster

High Availability setting

High Availability (HA) can be turned on or off for any cluster from the Cluster Overview page:

Enable High Availability - step 1 Enable High Availability - step 2

HA can be enabled for any cluster regardless of its size or other properties. This will create a special replica that will replace the cluster in case of a failure. You can learn more on the High Availability page.

Maintenance Window setting

The maintenance window for a cluster can be set or removed on the Cluster Settings page:

Set Maintenance Window

Protected setting

You can enable a flag called Protected on any cluster in the Cluster Settings page. This makes it impossible to destroy the cluster (until the flag is unset).

Other settings

Some aspects of a cluster can only be changed through Cluster Management maintenance operations. These operations require maintenance and should be initiated with care:

Immutable settings

Other aspects of a cluster cannot be changed directly, including:

  • Team ownership of a cluster
  • Provider or region where a cluster is provisioned

If you do want to change cluster ownership, or the provider or region where a cluster is provisioned, you have a couple of options. For clusters that are small in size and not being used in production, the easiest method is to use pg_dump to export the contents of the old cluster and pg_restore to import the contents into a newly provisioned cluster in the correct Team.

For larger or production databases, contact support and we can work with you on another method.
