Maintenance

On Timescale Cloud, minor software updates are handled automatically by us, and you do not need to perform any actions.

Non-critical software updates are applied during a maintenance window that you can define to suit your workload. If we detect a security vulnerability that affects you, we might need to perform maintenance outside of the scheduled maintenance window.

important

After a maintenance update, the DNS name remains the same, but the IP address it points to often changes.

Upgrades are performed as zero-downtime upgrades during maintenance windows. This means that there is no outage of your services during the upgrade. However, all connections and transactions in progress during the upgrade are reset. In most cases, the database connection is automatically restored after the reset.

Non-critical maintenance updates

Non-critical upgrades are made available before the upgrade is performed automatically. During this time you can click Apply upgrades to start the upgrade at any time. However, after the time expires, usually around a week, the upgrade is triggered automatically in the next available maintenance window for your service. You can configure the maintenance window so that these upgrades are started only at a particular time, on a set day of the week. If there are no pending upgrades available during a regular maintenance window, no changes are performed.

When you are considering your maintenance window schedule, you might prefer to choose a day and time that usually has very low activity, such as during the early hours of the morning, or over the weekend. This can help minimize the impact of a short service interruption. Alternatively, you might prefer to have your maintenance window occur during office hours, so that you can monitor your system during the upgrade.

Procedure: Adjusting your maintenance window

  1. Log in to your Timescale Cloud account. Click the name of the service that you want to manage the maintenance window for.
  2. In the Operations tab, navigate to the Maintenance section, and click Change maintenance window.
  3. In the Maintenance dialog, select the day of the week, the time, and the timezone that you want the maintenance window to start. Maintenance windows can run for up to four hours.
  4. Check Apply new maintenance window to all services if you want to use the same maintenance window settings for all of your Timescale Cloud services.
  5. Click Apply Changes.

Critical updates

Critical upgrades and security fixes are installed outside normal maintenance windows when necessary, and sometimes require a short outage.
