Upgrades and Maintenance

As a fully-managed service, the Redpanda Cloud control plane handles all maintenance operations, such as upgrades to your software and infrastructure.

Redpanda runs maintenance operations on clusters in a rolling fashion, accompanied by a series of health checks, so there is no disruption to the availability of your service. As part of the Kafka protocol, recycling nodes triggers client connections to be restarted. All mainstream client libraries support automatic reconnections when a restart occurs.

Maintenance windows

Redpanda Cloud may run maintenance operations on any day, at any time. You can override this default and schedule a specific maintenance window on your cluster’s Cluster settings page.

If you select a Scheduled maintenance window, then Redpanda Cloud runs operations on the day and time specified. Maintenance windows typically take six hours. All operations begin during your maintenance window, but some operations may complete after the window closes. All times are in Coordinated Universal Time (UTC).

Redpanda Cloud maintenance cycles always start on Tuesdays. Clusters scheduled for maintenance on Tuesdays are updated first, and clusters scheduled on Mondays are updated last. Keep this in mind when sequencing updates for multiple clusters.

Minor upgrades

During your defined maintenance window, Redpanda Cloud runs minor upgrades. Minor upgrades include standard Redpanda state changes that clients handle gracefully, such as leader elections.

At Redpanda’s discretion during your defined maintenance window.

Major upgrades

Major upgrades may require code changes to customer applications, such as Kafka clients or API integrations.

Category Details

Impact

Potentially large.

Private Service Connect v1

The Redpanda GCP Private Service Connect v2 service provides the ability to allow requests from Private Service Connect endpoints to stay within the same availability zone, avoiding additional networking costs.

To check the version of your Private Service Connect attachment, run:

gcloud compute service-attachments list --filter="region:( ${GCP_REGION} )"

The attachment name should show the suffix psc2; for example, projects/my-gcp-project/regions/us-west1/serviceAttachments/rp-d0f0mqk5ktzznib2j9g-psc2. If the name shows the suffix psc, then you have the deprecated version. To upgrade, contact Redpanda Support.
