MADlib, GPText, and PostGIS are not yet provided for installation on Ubuntu systems. Greenplum for Kubernetes is not yet provided with this release. The following table lists key known issues in VMware Tanzu availability and correctness in the event of a hardware failure. Kubernetes enables quick recovery from both pod and host failures, and Kubernetes storage services provide a high level of availability for the mirroring solutions. For these reasons, mirrorless deployments are fully supported with Greenplum for Kubernetes. Other deployment environments are generally not supported for production use unless both Greenplum

使用基于外部组件的资源组来管理外部组件的 CPU 和内存资源。这种资源组，使 用 cgroup 来管理外部组件的 CPU 和内存的使用总量。 注意：GP 的容器化部署，例如 Greenplum for Kubernetes(GP4K)，可能会创建 一组嵌套的 cgroup 配置来管理系统资源，这可能会影响 GP 的资源组管理 CPU 的使 用率、Core 数量和内存使用量，资源组的资源限制将受到上层资源配额的限制。
