Dedicated Control Plane Cells and Release Windows

By default, the WarpStream control plane is a multi-tenant regional service. Optionally, customers can purchase Dedicated Control Plane cells from Warpstream. Dedicated Control Planes provide full isolation from the other customers all the way from our external load balancer to the VMs running the WarpStream control plane, and the storage backing the cell. These dedicated control planes are spawned on demand and can be created in any region of any cloud provider.

Dedicated Control Plane cells are single-tenant to a given customer account, but users can provision any number of WarpStream Virtual Clusters in a given cell. Customers can also have multiple cells within an account. This flexibility enables Dedicated Control Plane cells to be isolated from other customers’ workloads, but also function as multitenant services within a single account, which improves cost efficiency and operational overhead.

Release Windows

In addition to fully dedicated infrastructure, Dedicated Control Planes enable customers to specify Release Windows. When a Release Window is specified, WarpStream will only apply code changes and feature flag updates within a specified 4 hour time window, once per week. The changes will track one of our multi-tenant control planes in a given region specified by the customer as of the previous Sunday. This means that regardless of your preferred Release Window, your dedicated cell will receive code changes that have been running in production for at least one day.

While Release Windows are intended to provide users with control over when a given Dedicated Control Plane cell receives routine code changes and feature flag rollouts, some critical changes may occur outside of the configured Release Window’s targeted release period, and WarpStream reserves the right to make these changes at its sole discretion. Changes that occur outside of the release period may include security updates, major bug fixes, or critical performance improvements that cannot wait until the next scheduled Release Window.

Non-automatable infrastructure changes may happen outside of the regularly scheduled maintenance windows for practical reasons, but even in these cases, Dedicated Control Planes are split into three different deployments in three different availability zones and manual infrastructures changes will be applied to only one deployment/zone at a time.

Release Windows are not available for standard control plane regions.
